Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a water tank overflow alarm device and an alarm method thereof. Background Art

[0002] Every construction project is typically designed with a domestic or fire water tank. These tanks are typically stainless steel and equipped with an overflow. The overflow drains into a nearby drain or sump. When the tank's supply pipe replenishes water, a mechanical float valve on the pipe controls the water level. However, due to manufacturing quality or long-term use, the float valve can become stuck and fail. If the float valve fails, the supply pipe will constantly replenish water, causing the tank overflow to overflow continuously. This can lead to significant water waste if unnoticed by inspectors. More seriously, excessive overflow could cause damage to surrounding equipment or risk electric shock, especially in areas with critical equipment that must be protected from water. Currently, there are no effective alarms for tank overflows. Summary of the Invention

[0003] In order to overcome the defects of the existing technology, a water tank overflow alarm device and an alarm method are now provided to solve the problem that there is no corresponding alarm measure for overflow water in existing domestic water tanks or fire water tanks.

[0004] To achieve the above object, a water tank overflow alarm device is provided, comprising:

[0005] A receiving box is arranged outside the water tank, wherein a through hole is opened on the side wall of the receiving box, and the through hole is connected to the overflow hole of the water tank through a horizontally arranged connecting pipe, and a drain pipe is connected to the bottom of the receiving box;

[0006] A humidity sensor for collecting the humidity value in the containing box, installed in the containing box;

[0007] A first conductive plate is reversibly mounted in the through-hole, one side of the reversible plate being supported on the bottom wall of the connecting pipe by a leg, a second conductive plate being mounted on the inner side of the side wall of the accommodating box, the first conductive plate and the second conductive plate being respectively connected to an alarm via a wire to form a disconnected circuit, water in the water tank flows into the connecting pipe through the overflow hole to push the first conductive plate, the first conductive plate being reversibly downward toward the inner side of the accommodating box and being attached to the second conductive plate to connect the circuit, causing the alarm to generate a water overflow signal;

[0008] a controller connected to the humidity sensor and the alarm, the controller acquiring the water overflow signal and the humidity value and sending an alarm signal when the humidity value exceeds a preset threshold;

[0009] A mobile terminal for receiving the alarm signal is connected to the controller.

[0010] Furthermore, the first conductive plate is tilted, and the tilt angle of the first conductive plate is 70° to 80°.

[0011] Furthermore, the first conductive plate and the second conductive plate are respectively installed with magnetic components, and the first conductive plate and the second conductive plate are magnetically adsorbed together by the magnetic components.

[0012] Furthermore, the humidity sensor is arranged at the bottom of the containing box.

[0013] Furthermore, the overflow hole is connected to a bell pipe, and the end of the communicating pipe away from the accommodating box is detachably inserted into the bell pipe.

[0014] Furthermore, one end of the connecting pipe is formed with an external thread, the socket pipe is formed with an internal thread, and one end of the connecting pipe is screwed into the socket pipe.

[0015] The present invention provides an alarm method for a water tank overflow alarm device, comprising the following steps:

[0016] Connect the accommodating box to the overflow hole of the water tank through a connecting pipe;

[0017] The humidity sensor collects the humidity value in the containing box;

[0018] When water in the water tank flows into the connecting pipe through the overflow hole to push the first conductive plate, the first conductive plate turns downward toward the inside of the accommodating box and fits against the second conductive plate to connect the circuit, causing the alarm to generate a water overflow signal;

[0019] The controller obtains the overflow signal and the humidity value, and sends an alarm signal to the outside when the humidity value exceeds a preset threshold;

[0020] The construction workers receive the alarm signal through the mobile terminal.

[0021] The beneficial effect of the present invention lies in that the water tank overflow alarm device is welded into a container using scrap materials such as stainless steel duct sheet material found on the construction site. This container is then fixed to the water tank interface at the same height as the water tank overflow hole. The bottom of the container is then connected to a drain pipe, and finally, a humidity sensor is placed in the container. When the water tank overflows, water from the overflow hole flows into the container, triggering the alarm through the first conductive plate. The controller generates an alarm signal based on the overflow signal from the humidity sensor, i.e., the alarm. Construction personnel receive the alarm signal through a mobile terminal and promptly address the water tank problem. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Combine Figure 2 and Figure 3 As shown, the first conductive plate 31 is installed in the through hole in a flip-up manner. One side of the flip plate is supported on the bottom wall of the connecting pipe 11 by a support leg 33.

[0036] As a preferred embodiment, see Figure 3 As shown, the first conductive plate 31 is tilted. The tilt angle of the first conductive plate 31 is 70° to 80°.

[0037] A second conductive plate 32 is installed on the inner side of the side wall of the container 1. The first conductive plate 31 and the second conductive plate 32 are respectively connected to an alarm through a wire to form a disconnected circuit.

[0038] The water in the water tank 5 flows into the connecting pipe 11 through the overflow hole to push the first conductive plate 31, and the first conductive plate 31 turns downward toward the inside of the accommodating box 1 and fits against the second conductive plate 32 to connect the circuit, so that the alarm generates a water overflow signal.

[0039] The controller 4 is connected to the humidity sensor 2 and the alarm. The controller 4 obtains the overflow signal and the humidity value and sends an alarm signal to the outside when the humidity value exceeds a preset threshold.

[0040] The mobile terminal is connected to the controller 4. The mobile terminal is used to receive alarm signals. In this embodiment, the mobile terminal is a portable device with accessibility, such as a mobile phone or tablet computer. Construction personnel receive alarm signals from the controller 4 through the mobile terminal and promptly address the problem with the water tank 5.

[0041] Continue reading Figure 3 As shown, in this embodiment, after the first conductive plate 31 is flipped by the overflowing water, magnetic elements are installed on each of the first and second conductive plates 31, 32 to ensure a tight fit between the first and second conductive plates 31, 32. The first and second conductive plates 31, 32 are magnetically attracted to each other by the magnetic elements, and the alarm generates a water overflow signal.

[0042] See Figure 2 As shown, the overflow hole of the water tank 5 is connected to a bell-and-spigot pipe 51. One end of the connecting pipe 11 away from the accommodating box 1 is detachably inserted into the bell-and-spigot pipe 51.

[0044] The present invention provides an alarm method for a water tank 5 overflow alarm device, comprising the following steps:

[0045] S1. Connect the accommodating box 1 to the overflow hole of the water tank 5 through the connecting pipe 11.

[0046] S2. The humidity sensor 2 collects the humidity value in the container 1.

[0047] S3. When the water in the water tank 5 flows into the connecting pipe 11 through the overflow hole to push the first conductive plate 31, the first conductive plate 31 turns downward toward the inner side of the accommodating box 1 and fits onto the second conductive plate 32 to connect the circuit, so that the alarm generates a water overflow signal.

[0048] S4. The controller 4 obtains the overflow signal and the humidity value, and sends an alarm signal when the humidity value exceeds a preset threshold.

[0049] S5. Construction workers receive alarm signals via mobile terminals.

[0050] The water tank overflow alarm device of the present invention utilizes waste materials such as stainless steel duct sheeting found on construction sites, turning waste into valuable resources. The stainless steel sheeting is marked, cut, and welded into a container. This container is then secured to the water tank interface at the same height as the tank's overflow hole. The bottom of the container is then connected to a drain pipe, and a humidity sensor is placed inside the container. When the water tank overflows, water from the overflow hole flows into the container, triggering an alarm via a first conductive plate. A controller generates an alarm signal based on the overflow signal from the humidity sensor, i.e., the alarm. Construction personnel receive the alarm signal via a mobile terminal, allowing them to promptly address the water tank issue.
