Description

Technical Field

[0001] This utility model belongs to the field of metrology and testing equipment, specifically relating to an automatic lifting water supply device for the calibration of glass measuring instruments. Background Technology

[0002] Glass volumetric instruments are commonly used precision measuring tools in laboratories, and their capacity calibration is a crucial step in ensuring measurement accuracy. Currently, the calibration of glass volumetric instruments mainly employs the weighing method, which determines their capacity by measuring the mass of pure water contained within the glass volumetric instrument. According to the calibration procedures for glass volumetric instruments, during the calibration process, pure water must be poured into a storage bottle and placed at a height of 2 meters, allowing gravity to cause the water to flow into the glass volumetric instrument to be calibrated.

[0003] Currently, the common method used in laboratories from the National Institute of Metrology to provincial metrology institutes to place water storage bottles at high locations is to install a support platform on the wall and then manually move the water storage bottles filled with pure water to the 2-meter-high support platform. This manual moving method is not only labor-intensive but also poses safety hazards.

[0004] Furthermore, regulations stipulate that the water storage bottles need to be cleaned, which requires operators to frequently lift and lower the glass bottles from a high support platform. This operation is cumbersome and prone to accidents. Although some existing automatic calibration devices have solved some of the problems, most are complex in structure, expensive, and lack specific solutions for the automatic lifting and lowering of water storage bottles and water supply issues.

[0005] Therefore, there is an urgent need for an automatic lifting water supply device for the calibration of glass volumetric instruments that is simple in structure, safe in operation, and convenient in use, in order to solve the problems existing in the current technology and improve the safety and efficiency of glass volumetric instrument calibration. Therefore, overcoming the aforementioned technical problems and defects has become a key issue that needs to be addressed. Utility Model Content

[0006] The purpose of this invention is to overcome the defects in the prior art and thus realize an automatic lifting water supply device for glass volumetric instrument calibration. This device can automatically raise and lower the height of the water storage bottle and realize the automatic supply of pure water during glass volumetric instrument calibration. It has a simple structure, safe operation, and convenient use, and can significantly improve the safety and efficiency of glass volumetric instrument calibration.

Their specific structure is not the point of invention of this utility model and will not be described in detail here.

[0012] In the aforementioned automatic lifting water supply device for glass volumetric instrument calibration, the support frame is a rectangular groove with an open top, and one side of the support frame is fixedly connected to the slide module. The support frame is open on the side away from the slide module for easy access to the water storage bottle. The specific shape of the support frame is not the focus of this invention; it can be made in various shapes, as long as it can support the horizontally placed water storage bottle. Simple substitutions of its shape should be considered as not exceeding the protection scope of this invention.

[0013] In the aforementioned automatic lifting water supply device for glass volumetric instrument calibration, the slide module includes a support beam, a slide rail, a lead screw, and a slide table arranged parallel to each other on the support beam. The slide table is slidably mounted on the slide rail and is installed in conjunction with the lead screw via a lead screw-nut pair. The support frame is fixedly mounted on the slide table.

[0031] The automatic lifting water supply device for glass volumetric instrument calibration of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] This embodiment discloses an automatic lifting water supply device for glass volumetric instrument calibration. This device can automatically raise and lower the height of the water storage bottle and automatically supply pure water during glass volumetric instrument calibration. It features a simple structure, safe operation, and ease of use, significantly improving the safety and efficiency of glass volumetric instrument calibration. Specifically, it mainly includes a frame base 1 for support and housing, a sliding table module 2, a support frame 3, a water storage bottle 4, a water supply mechanism 5, and an electrical control mechanism 6. The sliding table module 2 is vertically fixed on the frame base 1. The frame base 1 has sufficient strength and stability to ensure that the entire device will not shake or tilt during operation, guaranteeing the accuracy of glass volumetric instrument calibration. The bottom of the frame base 1 is fixedly equipped with lockable casters 8 for easy movement of the device.

[0034] Furthermore, a stepper motor 7 for driving the slide module 2 to rise and fall is provided on the top of the slide module, and the operation of the stepper motor is controlled by an electronic control mechanism. In this embodiment, see... Figure 4 The slide module 2 includes a support beam 201, a slide rail 202 parallel to the support beam, a lead screw 203, and a slide 204. The slide 204 is slidably mounted on the slide rail 202, providing guidance for the slide's movement. The slide is installed in conjunction with the lead screw 203 via a lead screw and nut pair. When the stepper motor 7 drives the lead screw to rotate, the slide can move up and down along the slide rail 202. The support frame 3 is fixedly mounted on the slide 204, and the slide drives the support frame 3 to lift and lower in the vertical direction. This design makes the movement of the slide more precise and controllable, enabling accurate positioning and meeting the precise control requirements for water level height during glass volumetric instrument calibration.

[0035] To achieve the purpose of automatically raising and lowering the height of the water storage bottle, see [link / reference]. Figure 2 and Figure 3 The support frame 3 is fixedly mounted on the slide module 2 and is driven to rise and fall by the slide module. The water storage bottle 4 is placed on the support frame 3 and is used to hold pure water to provide a water source for the calibration of glass measuring instruments. The water storage bottle is made of transparent material, which facilitates observation of water level changes and ensures a sufficient supply of pure water during the calibration process. In this embodiment, the support frame 3 is a rectangular groove with an open top, and one side of the support frame is fixedly connected to the slide module by bolts. The support frame 3 is open on the side away from the slide module, resembling a sieve. This design allows operators to easily put in or take out the water storage bottle 4, improving work efficiency. The shape and size of the support frame 3 match the water storage bottle, which can stably accommodate the water storage bottle 4 and prevent the water storage bottle from shaking or tilting during the lifting and lowering process. The specific shape of the support frame 3 is not the protection point of this utility model. It can be made into various shapes, as long as it can support the water storage bottle 4 placed horizontally. Simple replacement of its shape should be considered as not exceeding the protection scope of this utility model.

[0036] The water supply mechanism 5 is disposed within the frame base and is used to provide pure water to the water storage bottle 4. In this embodiment, see... Figure 2 and Figure 3 The water supply mechanism 5 includes a water storage tank 501, a water pump 502, a water pump switch 503, and a water delivery pipeline 504. The water storage tank 501 is located inside the frame base 1 and is used to store a certain amount of pure water to ensure continuous water supply. The water pump 502 and the water storage tank 501 are connected by the water delivery pipeline 504, and the water pump 502 outlet is downstream of the outlet. The outlet of the water delivery pipeline is inserted into the water storage bottle 4 to automatically supply pure water to the water storage bottle, forming a complete water supply system. The water pump switch 503 controls the start and stop of the water pump. The water pump switch 503 is located on the upper front side of the frame base 1 for easy operation by staff. The water pump switch 503 is a conventional push-button switch. It is turned on when pressed and turned off when pressed again. When water needs to be supplied to the water storage bottle 4, manually turn on the water pump switch 503. The water pump will draw out pure water from the water tank and deliver it to the water storage bottle 4 through the water supply pipeline 504. When the water level in the water storage bottle reaches the required level, manually turn off the water pump switch 503 to stop the water supply.

[0037] The electronic control mechanism 6 is housed within the frame base and is used to control the operation of the stepper motor. Specifically, the electronic control mechanism 6 is vertically fixed to the front sealing plate of the frame base 1 via a fixing plate 101 for easy maintenance. See also... Figure 5 and Figure 6 The electrical control mechanism includes a motor controller 601, a motor driver 602, a controller power supply 603, and a driver power supply 604. The controller power supply 603 is electrically connected to the motor controller 601, providing power to the motor controller. The motor controller 601 is electrically connected to the motor driver 602, responsible for sending control signals to the driver. The driver power supply 604 is electrically connected to the motor driver 602, providing power to the motor driver. The motor driver 602 is electrically connected to the stepper motor 7 at the top of the slide module, responsible for sending frequency signals to the stepper motor, driving the stepper motor 7 to achieve forward and reverse rotation. The main power switch 9 is used to cut off the external power supply. Through the electrical control mechanism, the speed, direction, and rotation angle of the stepper motor can be precisely controlled, thereby achieving precise lifting and lowering of the slide, meeting the precise control requirements of the water level height for glass volumetric instrument calibration.

[0038] To achieve manual wireless remote control, the electronic control mechanism also includes a wireless receiver 605 and a remote controller 606. The wireless receiver 605 receives operation signals sent by the remote controller. The wireless receiver 605 is electrically connected to the motor controller 601 and provides feedback signals to the motor controller. The driver power supply 604 is electrically connected to the wireless receiver 605 to provide power to the wireless receiver.

[0039] It should be noted that the motor controller, motor driver, controller power supply, driver power supply and wireless receiver are all mature existing technologies and can be directly purchased in the existing online or offline market. Their specific structure is not the point of invention of this utility model and will not be described in detail here.

[0040] The working principle of the glass volumetric instrument calibration lifting and water supply device of this utility model is as follows: First, the water storage bottle is placed on the support frame, and the water supply mechanism is started. The water pump draws out pure water from the water tank and delivers it to the water storage bottle. Then, the stepper motor is controlled by the electronic control mechanism to drive the lead screw on the slide module to rotate, thereby moving the slide and the support frame up and down to adjust the height of the water storage bottle. Finally, according to the needs of glass volumetric instrument calibration, pure water is continuously supplied to flow naturally from the water storage bottle to complete the calibration work.

[0041] The advantages of this design are as follows: Firstly, the height of the water bottle can be precisely controlled through the cooperation of the slide module and the electronic control mechanism, meeting the accuracy requirements of glass volumetric instrument calibration. Secondly, the water supply mechanism can provide a stable pure water source, ensuring the continuity and reliability of the calibration process. In addition, the open design of the support frame makes it convenient for operators to pick up and put down the water bottle, improving work efficiency.
