TECHNICAL FIELD

[0001] The utility model relates to pipe trench water discharge technical field especially, relate to a pipe trench drainage device with liquid level alarm function. BACKGROUND

[0002] There are many glass steel pipes and related metal fixed connecting pieces in the pipe trench of large seawater desalination plant, and the exhaust pipe will discharge a lot of seawater to the pipe trench, at present, the water pump in the pipe trench of large seawater desalination plant is all through remote host computer operating switch, and there is no way to monitor in real time, if there is no timely drainage, a large amount of seawater existing in the pipe trench will corrode related metal pieces, and also can cause the glass steel pipe in the pipe trench to float and be damaged, when the pipe in the pipe trench is broken and cannot be found in time, more serious safety production accidents can be caused, and there is great safety hidden danger. SUMMARY

[0003] To solve the above technical problem, the utility model provides a pipe trench drainage device with liquid level alarm function.

[0004] The utility model discloses the following technical scheme is realized: pipe trench drainage device with liquid level alarm function, including electric cabinet, audible -visual annunciator, drainage pump, corrosion -resistant PE float ball switch, adjustable fixed bolster, the electric cabinet is connected with audible -visual annunciator, drainage pump, corrosion -resistant PE float ball switch respectively, the corrosion -resistant PE float ball switch is equipped with 3: first corrosion -resistant PE float ball switch, second corrosion -resistant PE float ball switch, third corrosion -resistant PE float ball switch, first corrosion -resistant PE float ball switch, second corrosion -resistant PE float ball switch, third corrosion -resistant PE float ball switch are installed on adjustable fixed bolster in proper order from below to top.

[0005] First corrosion -resistant PE float ball switch and second corrosion -resistant PE float ball switch can be adjusted fixed height position on adjustable fixed bolster.

[0006] The electric cabinet is connected with audible -visual annunciator, drainage pump, corrosion -resistant PE float ball switch through wire respectively.

[0007] First corrosion -resistant PE float ball switch, second corrosion -resistant PE float ball switch, third corrosion -resistant PE float ball are parallelly connected.

[0008] Compared with prior art, the utility model has the beneficial effect that: first corrosion -resistant PE float ball switch and second corrosion -resistant PE float ball switch are connected with electric cabinet, and the electric cabinet controls the automatic start and stop of the drainage pump according to the water level monitored by first corrosion -resistant PE float ball switch and second corrosion -resistant PE float ball switch, third corrosion -resistant PE float ball switch is arranged to detect whether there is a water leakage problem in the pipeline, and the audible -visual annunciator is controlled to alarm in time, and the structure is simple, and the pipeline and metal parts in the pipe trench can be effectively protected.

[0012] 1, sound and light alarm; 2, electric control box; 3, drainage pump; 4, adjustable fixed support; 5, third corrosion-resistant PE float switch; 6, second corrosion-resistant PE float switch; 7, first corrosion-resistant PE float switch. Specific implementation

[0013] Next, the utility model is further described in combination with the drawings and specific implementation, and it should be noted that the following described embodiments or between various technical features can be arbitrarily combined to form new embodiments without conflict.

[0014] Embodiment:

[0015] Please combine Figs. 1-2 The pipe trench drainage device with liquid level alarm function of the embodiment comprises an electric control box, a sound and light alarm, a drainage pump, corrosion-resistant PE float switches and adjustable fixed supports, the electric control box is connected with the sound and light alarm, the drainage pump and the corrosion-resistant PE float switches respectively, the corrosion-resistant PE float switches are provided with three first corrosion-resistant PE float switches, second corrosion-resistant PE float switches and third corrosion-resistant PE float switches, and the first corrosion-resistant PE float switches, the second corrosion-resistant PE float switches and the third corrosion-resistant PE float switches are sequentially installed on the adjustable fixed supports from bottom to top.

[0016] The first corrosion-resistant PE float switch and the second corrosion-resistant PE float switch can be adjusted in height on the adjustable fixed support.

[0017] The electric control box is connected with the sound and light alarm, the drainage pump and the corrosion-resistant PE float switches through wires respectively.

[0018] The first corrosion-resistant PE float switch, the second corrosion-resistant PE float switch and the third corrosion-resistant PE float switch are connected in parallel.

[0019] When the second float switch contacts the water level, the electric control box connects the power supply of the drainage pump, and the drainage pump starts the drainage work, when the water level is lower than the first float switch, the electric control box disconnects the power supply of the drainage pump, and the drainage pump stops draining.

[0020] There is a third float switch higher in position and connected with the electric control box, once the pipe trench liquid level reaches the third float switch, it indicates that there is a pipe leakage problem, the electric control box sends a signal to make the sound and light alarm work, reminding the staff to go to check and solve.

[0021] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application belong to the scope of protection required by the present application.
