Abstract
Description
Technical Field
[0001] This utility model relates to the field of water tank level monitoring technology, and in particular to a water tank level monitoring device. Background Technology
[0002] Water tank level refers to the liquid level of the water inside the tank. Managing and controlling the water level is crucial for different types of water tanks. Low water level: The water level in the tank is too low, which may not meet normal use or emergency needs such as fire fighting. Normal water level: The water level in the tank is within the designed or specified normal range, ensuring normal use. High water level: The water level in the tank is too high, possibly approaching or exceeding the tank's maximum capacity, posing a risk of overflow.
[0003] In existing technologies, an alarm is triggered when the water level in the tank exceeds the safety warning line. If the water level rises too quickly, the alarm response takes time, which may cause the water inside the tank to overflow. It is difficult to use the power of the rising water level to quickly and automatically discharge the water inside the tank, resulting in low safety performance. Therefore, a water tank level monitoring device is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the alarm sounding when the water level in the tank exceeds the safety warning line, the alarm response taking time if the water rises too quickly, which may cause water to overflow from the tank, making it difficult to use the rising water level to quickly and automatically discharge the water from the tank, resulting in low safety performance. Therefore, this invention proposes a water tank level monitoring device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A water tank level monitoring device includes a water tank body. An automatic water discharge mechanism is installed inside the water tank body. The automatic water discharge mechanism includes a connecting plate inside the water tank body. A float plate is fixedly connected to the side of the connecting plate away from the water tank body. A pressure rod is fixedly connected to the side of the connecting plate away from the float plate. A connecting pipe is installed below the pressure rod. A baffle is installed at one end of the pressure rod near the inside of the connecting pipe. A fixing rod is fixedly connected to the side of the baffle away from the connecting pipe. A first gear is fixedly connected to the side of the fixing rod away from the baffle. A rack and belt are engaged, and a second gear is engaged on the side of the rack and belt away from the first gear. The float is rotated by the rising water source. The float moves the pressure rod through the connecting plate. The pressure rod rotates inside the connecting pipe by pressing the baffle. The baffle drives the first gear to rotate through the fixed rod. The first gear drives the second gear to rotate through the rack and belt. Another set of connecting pipes is connected to the side of the second gear away from the rack and belt. The baffle rotates inside the connecting pipe and causes the water source to be discharged through multiple sets of connecting pipes.
[0007] The above technical solution further includes:
[0008] The water tank body is provided with a float plate, the connecting plate is rotatably connected to the water level tank, and the connecting pipe is fixedly connected to the water level tank.
[0009] A drain pipe is fixedly connected to the side of the connecting pipe away from the baffle.
[0010] The drainage pipes are provided in multiple sets, with each set of connecting pipes corresponding to a set of drainage pipes.
[0011] The water tank body has an installation groove on the side near the water level tank.
[0012] The water tank is equipped with a display screen on its side to show water level information.
[0013] A sensor strip is installed on the side of the water tank near the water level trough to monitor the water level.
[0014] The water tank is fixedly connected to the top of the tank body with an inlet pipe, and to the bottom of the tank body with an outlet pipe. An alarm light is installed on the side of the tank body.
[0015] This utility model has the following beneficial effects:
[0016] In this invention, an automatic water discharge mechanism composed of a float, connecting plate, pressure rod, baffle, and connecting pipe can quickly and automatically open the drainage channel when the water level inside the tank exceeds the safety warning line, effectively preventing water overflow caused by delayed alarm response. This design not only improves drainage efficiency but also enhances the safety performance of the device.
[0017] In this invention, the meshing connection of the first gear, rack and belt, and second gear enables synchronous rotation and drainage of the multi-stage connecting pipes, thereby significantly improving the drainage volume and speed. This multi-stage linkage design allows the device to respond more quickly and effectively to rapidly rising water levels.
[0018] In this invention, the display screen on the side of the water tank can show the water level in real time, while the sensor strip can accurately monitor changes in the water level. When the water level exceeds the safety limit, the alarm light will immediately illuminate and an alarm sound will be emitted, reminding staff to take timely measures. This real-time monitoring and alarm function provides strong protection for the safe operation of the device. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0026] like Figures 1-5 As shown, the present invention proposes a water tank level monitoring device, including a water tank body 1. An automatic water discharge mechanism is installed inside the water tank body 1. The automatic water discharge mechanism includes a connecting plate 2 inside the water tank body 1. A float 3 is fixedly connected to the side of the connecting plate 2 away from the water tank body 1. A pressure rod 5 is fixedly connected to the side of the connecting plate 2 away from the float 3. A connecting pipe 7 is installed below the pressure rod 5. A baffle 6 is installed at one end of the pressure rod 5 near the inside of the connecting pipe 7. A fixing rod 8 is fixedly connected to the side of the baffle 6 away from the connecting pipe 7. A first gear 9 is fixedly connected to the side of the fixing rod 8 away from the baffle 6. A rack belt 10 is engaged with the side of the rack belt 10, and a second gear 11 is engaged with the side of the rack belt 10 away from the first gear 9. The float 3 is driven to rotate by the rising water source. The float 3 drives the pressure rod 5 to move through the connecting plate 2. The pressure rod 5 rotates inside the connecting pipe 7 by pressing the baffle 6. The baffle 6 drives the first gear 9 to rotate through the fixed rod 8. The first gear 9 drives the second gear 11 to rotate through the rack belt 10. Another set of connecting pipes 7 is connected to the side of the second gear 11 away from the rack belt 10. The baffle 6 rotates inside the connecting pipe 7 and causes the water source to be discharged through multiple sets of connecting pipes 7.
[0027] A float plate 3 is provided inside the water tank body 1. The connecting plate 2 is rotatably connected to the water level tank 4, and the connecting pipe 7 is fixedly connected to the water level tank 4.
[0028] A drain pipe 12 is fixedly connected to the side of the connecting pipe 7 away from the baffle 6.
[0029] In this embodiment, when the water level inside the water tank 1 rises to the warning level, the rise in water will activate the automatic water discharge mechanism. The rising water level causes the float 3 to move, which in turn causes the connecting plate 2, which is fixedly connected to its side, to rotate. The connecting plate 2 rotates at the protrusion of the water level groove 4 inside the water tank 1. As the connecting plate 2 rotates, it causes the pressure rod 5, which is fixedly connected to its other side, to move. The other end of the pressure rod 5 is located inside the connecting pipe 7 near the baffle 6. The pressure rod 5 begins to press down inside the connecting pipe 7, causing the baffle 6 to rotate inside the connecting pipe 7. At this point, the internal space of the connecting pipe 7 is no longer sealed, and water begins to flow through. Discharge is carried out through connecting pipe 7. Baffle 6 passes through the inside of connecting pipe 7 and is fixedly connected to fixed rod 8. When baffle 6 rotates, it drives fixed rod 8 to rotate. When fixed rod 8 rotates, it drives first gear 9, which is fixedly connected to its other side, to rotate. When first gear 9 rotates, it drives rack belt 10, which is meshed with its side, to rotate. When rack belt 10 rotates, it drives second gear 11, which is meshed with its other side, to rotate. Second gear 11 will drive another set of baffle 6 to rotate using the same principle, so that multiple sets of connecting pipes 7 can carry out drainage work at the same time. When the water flow exceeds the warning water level, it can quickly and automatically carry out drainage work. Example

[0031] A display screen 14 is provided on the side of the water tank body 1 to display water level information.
[0032] A sensor strip 15 is installed on the side of the water tank body 1 near the water level tank 4 to monitor the water level.
[0033] A water inlet pipe 16 is fixedly connected to the top of the water tank body 1, a water outlet pipe 17 is fixedly connected to the bottom of the water tank body 1, and an alarm light 18 is installed on the side of the water tank body 1.
[0034] In this embodiment, an installation groove 13 is provided inside the water tank body 1. The fixing rod 8, the first gear 9, the rack belt 10, and the second gear 11 are all installed inside the installation groove 13 to maintain the stability of its operation. A sensing strip 15 is fixedly connected inside the water tank body 1. The sensing strip 15 can monitor the water level inside the water tank body 1 in real time and transmit the water level information to the display screen 14 set on the side of the water tank body 1. The display screen 14 displays the water level information for easy inspection by staff. The water source enters the water tank body 1 through the water inlet pipe 16 at the top of the water tank body 1 and is discharged through the water outlet pipe 17 fixedly connected to the bottom of the water tank body 1 for people to use. Two sets of alarm lights 18 are symmetrically arranged on the side of the water tank body 1. The two sets of alarm lights 18 are used to remind staff that the water level exceeds the safety limit and to sound an alarm.
