Description

Technical Field

[0001] The utility model relates to the technical field of water level sensors, in particular to a water level sensor calibration and testing device. Background Art

[0002] A water level sensor refers to an instrument that can convert the water level parameter of the measured point into a corresponding electrical signal in real time. Its working principle is: the water level sensor in the container transmits the sensed water level signal to the controller, and the computer in the controller compares the measured water level signal with the set signal to obtain the deviation, and then sends "open" and "close" instructions to the water supply electric valve according to the nature of the deviation to ensure that the container reaches the set water level. In the production process of the water level sensor, it is necessary to test the measurement accuracy of the sensor. In the process of testing the measurement accuracy of the sensor, a detection instrument is generally used for detection. Based on the above, the existing water level sensor detection instrument can only detect the test accuracy when the water level is relatively calm during use. However, shaking conditions are often encountered during use. The existing accuracy detection device cannot well reflect the accuracy under actual use conditions. The test is divorced from reality and cannot meet the test needs. Utility Model Content

The existing accuracy detection device cannot well reflect the accuracy under actual use conditions, the test is divorced from reality, and cannot meet the test needs.

[0005] The water flow structure includes a base with a display controller fixed on one side, a water tank with scale lines on the surface fixed on the base, and a manual regulating valve embedded in front of the water tank;

[0006] A valve pipe for conveying through the water tanks is inlaid and installed between the water tanks, and a conveying pipe connected to the high-pressure water pump is installed between the water tanks.

[0007] By adopting the above technical solution, the one-way transportation is enabled by the arranged valve pipe.

[0008] Preferably, the installation and adjustment structure includes a through-hole mounting platform fixed to the water tank, and a rotating motor is fixed to the rear side of the through-hole mounting platform, and an eccentric disk is fixed to the output end of the rotating motor.

[0009] By adopting the above technical solution, the through-hole mounting platform is provided to achieve fixing and penetrating fixing installation.

[0010] Preferably, the eccentric disk is rotatably mounted with a through-hole connecting plate via a connecting pin, and one end of the through-hole connecting plate is also rotatably connected to one end of the adjusting connecting plate via a connecting pin, while the other end of the adjusting connecting plate is rotatably connected to one end of another through-hole connecting plate.

[0019] (1) This case is provided with: installing an adjustment structure, thereby solving the problem that the existing water level sensor detection instrument can only detect the test accuracy when the water level is relatively calm during use. However, it often encounters a shaking state during use. The existing accuracy detection device cannot well reflect the accuracy under the actual use state. The test is out of touch with reality and cannot meet the test requirements. When the water level sensor needs to be calibrated and tested, the operator manually fixes the water level sensor inside the through block and controls the rotation motor to operate. During the operation of the rotation motor, the through-hole plate and the water level sensor are driven by the eccentric disk to adjust the force synchronously.

The operator can open the valve pipe to allow the water in the large water tank to flow into the small water tank, thereby changing the water height distance inside the large water tank, making it convenient to calibrate and test the water level sensor with water at different heights.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution: a water level sensor calibration and testing device, such as Figure 1 and Figure 2As shown, it includes a water flow structure 1, which includes a base 101 with a display controller fixed on one side, and a water tank 102 with scale lines 103 on the surface is fixed on the base 101, and a manual regulating valve 104 is embedded and installed in front of the water tank 102. A group of water tanks 102 are provided, and the water tanks 102 adopt different volume settings. When the above-mentioned components are provided in one group, it not only reflects the practicality of the installation setting of the above-mentioned components, but also reflects the mutual water transmission and transferability of the above-mentioned components. When the water tanks 102 adopt different volume settings, it is not only convenient to change the water depth height inside the water tank 102, but also effectively achieves a flexible calibration and inspection effect on the water level sensor by changing the water height distance.

[0028] Furthermore, in the above scheme, a valve pipe 105 for conveying water is embedded between the water tanks 102 , and a conveying pipe 106 connected to a high-pressure water pump 107 is installed between the water tanks 102 .

[0029] like Figure 3 and Figure 4 As shown, a mounting and adjusting structure 2 is fixed on the water flow structure 1, and the mounting and adjusting structure 2 includes a through-hole mounting platform 201 fixed to the water tank 102, and a rotating motor 202 is fixed to the rear side of the through-hole mounting platform 201, and an eccentric disk 203 is fixed to the output end of the rotating motor 202.

[0030] The above scheme further, the eccentric disk 203 is rotatably installed with a through-hole connecting plate 204 through a connecting pin, and one end of the through-hole connecting plate 204 is also rotatably connected to one end of the adjusting connecting plate 205 through a connecting pin, and at the same time, the other end of the adjusting connecting plate 205 is rotatably connected to one end of another through-hole connecting plate 204, and the overall shape of the adjusting connecting plate 205 is set in a "V" shape. When the overall shape of the above-mentioned parts is set in a "V" shape, it can be clearly known that the adjusting connecting plate 205 is in the maximum folding state at this time, and the through-hole plate 206 is in the highest adjustment distance range when the adjusting connecting plate 205 is in the maximum folding state. By continuously changing the relative angle of the adjusting connecting plate 205, the lifting interval distance of the through-hole plate 206 is synchronously changed, which effectively plays a flexible verification and inspection of the water level sensor, wherein, the connecting plates 205 are installed with a connecting nut group, thereby ensuring that the different folding angles of the adjusting connecting plate 205 are adjusted and locked to limit.

[0031] Furthermore, in the above scheme, the other end of another through-hole connecting plate 204 is also rotatably connected to the through-hole plate 206 via a connecting pin, and a through block 207 with a threaded hole is fixed in front of the through-hole plate 206, and the through block 207 is threadedly connected to the rotating nut via the threaded hole.

[0032] In the above scheme, after the operator manually fixes the water level sensor inside the through block 207, the rotating motor 202 is controlled to operate. During the operation of the rotating motor 202, the through-hole plate 206 and the water level sensor are driven to synchronously adjust the force through the eccentric disk 203. When it is necessary to change the distance at which the water level sensor detects water, the operator rotates the adjusting connecting plate 205 to lower or retract the through-hole plate 206 to change the contact distance height between the water level sensor and the water, thereby changing the water level sensor's detection of different water levels. After adjusting the height of the water level sensor, the operator can change the water height inside the water tank 102 through the valve pipe 105 or the high-pressure water pump 107 to flexibly adjust and test the water level sensor and the reverse flow.
