Technical Field

[0001] This utility model relates to an automatic alarm device for water leakage in a medium frequency cabinet, belonging to the technical field of auxiliary tools for electrolytic aluminum production. Background Technology

[0002] In electrolytic aluminum production workshops, intermediate frequency cabinets are considered major hazard sources. Improper use or maintenance can lead to risks of electric shock, fire, arc burns, and even explosions. The operation of intermediate frequency cabinets relies on cooling water pipes for cooling. If these pipes become detached or leak, and are not detected and addressed promptly, it can cause dangerous situations such as equipment discharge, component breakdown, or equipment tripping; furthermore, it can even lead to a safety accident. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic alarm device for water leakage in intermediate frequency cabinets, which can detect water leakage in the cooling water pipes inside the intermediate frequency cabinets in a timely manner and issue an alarm to avoid safety accidents caused by water leakage in the intermediate frequency cabinets.

[0004] This utility model discloses an automatic alarm device for water leakage in a medium frequency cabinet, which includes a container box. Several electrometric funnels for collecting liquid are arranged inside the container box. A drawer for storing liquid is provided at the bottom of the container box, and an absorbent plate for absorbing liquid is provided inside the drawer.

[0005] The measuring funnel includes: a liquid collecting hopper, with a flow guide strip inside the hopper for guiding the liquid flow, and a measuring cup for receiving the liquid connected to the liquid outlet at the lower end of the hopper; the measuring cup contains electrodes.

[0006] Furthermore, the container includes: a box body, with a partition island on the box body, the partition island being connected to the connection point of the measuring funnel; a storage compartment is provided at the bottom of the box body, and a drawer is movably connected inside the storage compartment.

[0007] Furthermore, the drawer box has a fixing hole on its side for traction.

[0008] Furthermore, the measuring cup is made of insulating material.

[0009] Furthermore, the electrodes are arranged in pairs, and the electrodes are electrically connected to an external alarm device; the electrodes and the conductive liquid inside the measuring cup together form a circuit loop.

[0010] Furthermore, the drainage strip extends from the opening at the top of the collection hopper to the outlet at the bottom of the collection hopper.

[0011] The advantages of this utility model compared with the prior art are:

[0012] This invention uses a measuring funnel to collect liquid seeping into the pipes inside the intermediate frequency cabinet. By utilizing the conductivity of the liquid, it triggers a circuit alarm. This invention only requires the detection of a small amount of leaked liquid to trigger an alarm, thus facilitating timely detection and warning in the early stages of liquid leakage and preventing safety accidents caused by delayed detection leading to the expansion of the leak.

[0024] like Figure 1-5 As shown, this embodiment is achieved through the following technical solution: it includes a container 1, in which a plurality of electrical measuring funnels 2 for collecting liquid are arranged, and a drawer box 3 for storing liquid is provided at the bottom of the container 1. The drawer box 3 is provided with an absorbent plate 4 for absorbing liquid; the absorbent plate 4 absorbs the liquid to prevent the liquid from accumulating and flowing, thereby preventing the liquid from spilling from the drawer box 3 into the intermediate frequency cabinet 5 when the drawer box 3 is taken out.

[0025] The measuring funnel 2 includes: a liquid collecting funnel 201, a flow guide strip 202 for guiding liquid flow inside the liquid collecting funnel 201, and a measuring cup 203 for receiving liquid connected to the liquid outlet at the lower end of the liquid collecting funnel 201; the measuring cup 203 is provided with an electrode 204.

[0026] Specifically, the container 1 includes: a container body 103, with a partition island 102 on the container body 103, the partition island 102 being connected to the connection point of the current measuring funnel 2; a storage compartment 101 is provided at the bottom inside the container body 103, and a drawer 3 is movably connected inside the storage compartment 101; the partition island 102 protrudes from the top of the container body 103, the partition island 102 prevents leaked liquid from remaining on the surface of the container body 103, and the partition island 102 guides the leaked liquid to the nearest current measuring funnel 2, so that the current measuring funnel 2 can detect the leaked liquid in a timely manner.

[0027] Specifically, the drawer box 3 has a fixing hole 301 on its side for pulling. A tool is used to hang the drawer box 3 into the fixing hole 301 so that it can be taken out of the container box 1.

[0028] Specifically, the measuring cup 203 is made of insulating material.

[0029] Specifically, electrodes 204 are arranged in pairs and are electrically connected to an external alarm device; electrodes 204 and the conductive liquid in the measuring cup 203 together form a circuit loop.

[0030] In this embodiment, the alarm device is an audible and visual alarm module. When the measuring cup 203 does not contain conductive liquid, the electrode 204 is normally open. At this time, the circuit of the alarm device is open and the alarm device is off. When the electrodes 204 are connected, the circuit of the alarm device is closed. At this time, the device sends out audible and visual signals to trigger an alarm.

[0031] Specifically, the drainage strip 202 extends from the opening at the upper end of the liquid collecting hopper 201 to the outlet at the lower end of the liquid collecting hopper 201.

[0032] The specific operating principle is as follows: When liquid leakage occurs inside the intermediate frequency cabinet 5, the liquid gathers towards the bottom of the intermediate frequency cabinet 5 under the action of gravity. This utility model is installed at the bottom of the intermediate frequency cabinet 5. See details. Figure 5 Furthermore, the liquid first gathers in the measuring funnel 2, and the guide strip 202 assists the liquid to flow quickly to the bottom of the collecting hopper 201. Finally, the liquid flows into the measuring cup 203, and the electrodes 204 in the measuring cup 203 are connected, and the alarm device is activated. Excess liquid overflows from the measuring cup 203 and flows into the drawer 3. Furthermore, the absorbent sheet 4 absorbs the liquid.

[0033] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
