Description

Technical Field

[0001] This utility model relates to an automated alarm system for emergency circulating water sources, belonging to the field of electrolytic aluminum production technology. Background Technology

[0002] The circulating emergency water source used in the electrolytic aluminum anode workshop is prone to leaks, which can flow into a sump, requiring constant monitoring by workers. Therefore, an automatic alarm device is installed, with wiring laid along the ground to connect to the alarm light in front of the furnace. However, due to various factors during use, the wiring may age, wear down, and ground, potentially causing electric shock to personnel and affecting the lifespan of the equipment, thus posing a safety hazard. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an automated alarm system for emergency circulating water sources to solve the above problems.

[0004] The circulating water emergency water source automatic alarm system of this utility model includes a wireless audible and visual alarm and a signal transmitter. The circuit of the signal transmitter is equipped with a contact switch. The contact switch is located in the leakage sump and is controlled by a liquid level sensing device. When there is water in the leakage sump, the contact switch is turned on, the circuit of the signal transmitter is turned on and sends a signal to trigger the wireless audible and visual alarm.

[0005] The liquid level sensing device is a float-type sensing device.

[0006] Specifically, the float-type sensing device includes a float, which is connected to one end of a lever via a connecting rod. The lever is mounted on a fixed crossbeam above the leakage sump via a hinge point. The other end of the lever is pressed against a contact switch, which has a reset disconnect device.

[0007] Furthermore, the connecting rod is slidably disposed within the fixed sleeve, with the top of the connecting rod hinged to the sliding sleeve, and the sliding sleeve fitted onto the lever.

[0008] Preferably, the reset disconnection device is a compression spring.

[0009] The beneficial effects of this utility model compared with the prior art are as follows: The automatic alarm system for emergency circulating water source of this utility model can effectively reduce on-site safety hazards, improve the level of automation, extend the service life of the alarm device, and prevent accidents of electric shock.

[0013] The present invention will be further described below with reference to specific embodiments.

[0014] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.

[0015] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0016] like Figure 1 , 2 As shown, this embodiment is achieved through the following technical solution: it includes a wireless sound and light alarm 1 and a signal transmitter 2. The circuit of the signal transmitter 2 is equipped with a contact switch 3. The contact switch 3 is located in the leakage sump 5. The contact switch 3 is controlled by a liquid level sensing device. In this embodiment, the liquid level sensing device is a float-type sensing device.

[0017] The float-type sensing device includes a float 6, which is connected to one end of a lever 10 via a connecting rod 7. The lever 10 is mounted on a fixed crossbeam 12 above the leakage sump 5 via a hinge point 11. The other end of the lever 10 is pressed against a contact switch 3, which has a reset and disconnect device. The connecting rod 7 is slidably mounted inside a fixed sleeve 8, and the top of the connecting rod 7 is hinged to a sliding sleeve 9, which is fitted onto the lever 10.

[0018] In this embodiment, the reset disconnection device is a compression spring 4.

[0019] In this embodiment, two wires are led out from the internal contacts of the signal transmitter 2 and connected to the contact switch 3. When there is water in the leakage pit 5, the float 6 rises, lifting one end of the lever 10. The other end of the lever 10 presses down on the contact switch 3, causing its contacts to open. The circuit of the signal transmitter 2 is activated, sending a signal to the wireless audible and visual alarm 1, thus achieving the wireless alarm requirement. After the leakage pit 5 is drained, the liquid level drops, compressing the spring 4 and causing the contact switch 3 to reset and open. This utility model realizes wireless remote alarm, avoids safety hazards caused by line faults, improves the service life of the alarm device, and achieves automation and standardization.

[0020] 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.
