Description

Technical Field

[0001] This utility model relates to the field of gas detection and calibration technology, and in particular to a calibration device for an ammonia detector. Background Technology

[0002] Ammonia is an important inorganic compound with the chemical formula NH3. It is easily soluble in water and is a colorless gas at room temperature and pressure. Ammonia detector calibration devices are based on the comparison between the concentration of a standard gas and the instrument's response value. By releasing ammonia standard substance of known concentration, the device detects whether the instrument can accurately identify and alarm. It is widely used in chemical, agricultural, and environmental protection fields to ensure the accuracy and reliability of ammonia detectors in fertilizer production, wastewater treatment, industrial safety and other scenarios.

[0003] Currently, most ammonia detector calibration devices typically involve placing a cylinder containing ammonia on the floor and testing it using the calibration structure. Due to its rounded structure, the cylinder is prone to tipping over upon impact, causing damage to the device and affecting the experimental process.

[0004] Therefore, designing a calibration device for an ammonia detector that can be placed stably and is not prone to tilting or collapsing is a technical problem that technicians need to solve. Utility Model Content

[0005] The purpose of this invention is to provide a calibration device for an ammonia detector. The support frame is set up at a 60-degree angle to the floor, which can provide support. With the assistance of the sealing gasket, the piston is pulled upward, which can cause the counterweight to adhere to the floor, making it less likely to tilt or collapse. This effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ammonia detector calibration device, comprising a counterweight, a detector calibration structure, and two fixed cylinders. The detector calibration structure and the fixed cylinders are connected to the counterweight. Each of the two fixed cylinders contains a gas cylinder, one of which stores ammonia and the other contains air. A multi-connector is connected between the two gas cylinders, and the output end of the multi-connector is connected to the detector calibration structure.

[0007] It also includes:

[0008] Two sets of support components are respectively fitted onto the outer walls of two fixed cylinders to support the overall device and promote its stability;

[0009] The adsorption component, mounted on the counterweight, creates a negative pressure inside, allowing the device to adhere stably to the base plate, thus enhancing stability.

[0010] Preferably, the support assembly includes a collar and three folded support frames, which are rotatably connected to the fixed cylinder and the collar, thereby improving stability by unfolding the three support frames.

[0011] Preferably, the adsorption assembly includes a connecting cylinder and a piston. The connecting cylinder is disposed on a counterweight base, and a sealing gasket is provided on the outer wall of the connecting cylinder located on the lower surface of the counterweight base. The piston moves up and down on the inner wall of the connecting cylinder, which can cause a negative pressure state to be formed inside the connecting cylinder.

[0012] Preferably, a connecting plate is provided between the two fixed cylinders, and two guide rods are provided between the connecting plate and the counterweight. A fixed plate and a limiting block are sleeved on the two guide rods. The limiting block is connected to the piston, and the fixed plate is connected to two collars.

[0013] Preferably, a bidirectional lead screw is rotatably provided on the connecting plate, and the bidirectional lead screw thread passes through the fixing plate and the limiting block.

[0014] Preferably, a mounting ring is provided at the lower end of the outer wall of the fixed cylinder, and a spring is provided between the mounting ring and the collar to cause the collar to reset.

[0015] Preferably, the size of the limiting block is smaller than the size of the fixing plate.

[0016] Preferably, the maximum rotation range of the support frame is sixty degrees.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: by rotating the bidirectional lead screw, the collars on both sides of the fixed plate are pressed down, causing the collars to press down on the support frame to unfold. When the support frame is at a 60-degree angle to the ground, it is stable enough. The rotation of the bidirectional lead screw causes the limiting block to drive the piston to move upward from the bottom of the connecting cylinder. With the assistance of the sealing gasket, the inside of the connecting cylinder will be in a negative pressure state, so that the counterweight is firmly adsorbed and fixed to the floor, thus achieving fixation and preventing easy collapse.

[0032] The technical solution of the present utility model embodiment is described in detail below with reference to the accompanying drawings. An ammonia detector calibration device includes a counterweight 1, a detector calibration structure 3 and two fixed cylinders 4. The detector calibration structure 3 and the fixed cylinders 4 are connected to the counterweight 1. Each of the two fixed cylinders 4 is provided with a gas cylinder 2. One gas cylinder 2 stores ammonia and the other gas cylinder 2 stores air. A multi-connector 11 is connected between the two gas cylinders 2. The output end of the multi-connector 11 is connected to the detector calibration structure 3.

[0033] It also includes:

[0034] Two sets of support components 5 are respectively fitted onto the outer walls of the two fixed cylinders 4 to support the overall device and promote its stability;

[0035] The adsorption component 6 is set on the counterweight 1. By creating a negative pressure inside it, the device can be stably adsorbed onto the base plate, thus enhancing stability.

[0036] The support assembly 5 includes a collar 51 and three folded support frames 52, which are rotatably connected to the fixed cylinder 4 and the collar 51. The unfolding of the three support frames 52 is used to improve stability.

[0037] The adsorption assembly 6 includes a connecting cylinder 61 and a piston 64. The connecting cylinder 61 is mounted on the counterweight 1. A sealing gasket 62 is provided on the outer wall of the connecting cylinder 61 on the lower surface of the counterweight 1. The piston 64 moves up and down on the inner wall of the connecting cylinder 61, which can cause a negative pressure state to be formed inside the connecting cylinder 61.

[0038] A connecting plate 7 is provided between the two fixed cylinders 4. Two guide rods 8 are provided between the connecting plate 7 and the counterweight seat 1. A fixed plate 9 and a limiting block 63 are sleeved on the two guide rods 8. The limiting block 63 is connected to the piston 64. The fixed plate 9 is connected to the two collars 51.

[0039] A bidirectional lead screw 10 is rotatably mounted on the connecting plate 7, and the bidirectional lead screw 10 is threaded through the fixing plate 9 and the limiting block 63.

[0040] A mounting ring 53 is provided at the lower end of the outer wall of the fixed cylinder 4. A spring 54 is provided between the mounting ring 53 and the collar 51 to cause the collar 51 to reset.

[0041] The size of the limiting block 63 is smaller than the size of the fixing plate 9.

[0042] The maximum rotation range of the support frame 52 is 60 degrees.

[0043] Example 1: Reference Figures 1 to 3 , Figure 5 , Figure 6 To address the issue of the calibration device tilting and collapsing due to impact or vibration during testing, the technical solution implemented here is as follows: Since the counterweight 1 is made of metal, it serves as a stable center. Furthermore, under the limiting action of the guide rod 8, the rotation of the bidirectional lead screw 10 causes the fixing plate 9 to move downward, thereby squeezing the collars 51 on both sides downward. This allows the support frame 52 to be rotated outward and supported on the floor due to the rotatable connection between the support frame 52 and the fixing cylinder 4, forming a 60-degree support angle with the floor. By increasing the number of contact points and designing it in a triangular shape, the overall stability is improved, making it less prone to collapse.

[0044] Example 2: Based on Example 1, with reference to... Figures 2 to 4 To further address the issue of insufficient stability of the calibration device during testing, the specific technical solution is as follows: Under the rotation of the bidirectional lead screw 10, the limiting block 63 will rotate upward, which will drive the piston 64 inside the connecting cylinder 61 to move upward from the bottom. With the assistance of the sealing gasket 62, the piston 64 moves all the way to the upper third position inside the connecting cylinder 61, creating a negative pressure state inside, thereby firmly adhering and fixing it to the floor, making the device less prone to tilting and collapsing when impacted.
