Description

Technical Field

[0001] The utility model relates to the field of environmental monitoring, in particular to an infrared spectrophotometer for measuring oil. Background Art

[0002] The infrared spectrophotometer is an instrument that uses infrared spectrophotometry to determine petroleum and animal and vegetable oils. It can perform simple and rapid detection of petroleum and animal and vegetable oils in industrial wastewater and domestic sewage. It can more accurately reflect the degree of pollution of oil substances in industrial wastewater and domestic sewage, and plays an important role in environmental monitoring.

[0003] Although the infrared spectrophotometer is heavy and large in size, it is more suitable for on-site use than in the laboratory. For example, after a simple calibration of the instrument on site, you only need to insert the sample into the measurement hole, and the monitoring data can be obtained in a few minutes. Based on the test data, you can promptly determine whether the same location needs to be retested, and retest quickly. Compared with running back and forth between the laboratory and the site, using the infrared spectrophotometer on site saves a lot of time and simplifies the process.

[0004] However, when using existing infrared spectrophotometers, it is usually necessary to manually move the oil meter between different monitoring points. Even if a cart or transport vehicle is used, the infrared spectrophotometer needs to be constantly moved up and down because it needs to work in a stable and balanced state. The process is also cumbersome, time-consuming and labor-intensive. As a field detection device, the oil meter cannot be easily moved, which leads to low efficiency in environmental monitoring.

[0042] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0043] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0044] See also Figure 1-3 This embodiment provides an infrared spectrophotometer for measuring oil, which mainly includes: a detection component 100, a lifting component 200 and a moving component 300.

[0045] like Figure 1 , Figure 2 As shown in the figure, the detection component 100 is roughly in the shape of a horizontal rectangular parallelepiped, and is used to measure the oil content in the sample. Outside the detection component 100, a detection port 110 for placing the sample and an operation panel 120 are provided on the upper surface. Inside the detection component 100, a sample injection system connected to the detection port 110, as well as an extraction system, an adsorption and filtration system, and a detection system are provided, and the detection results can be quickly and automatically displayed on the operation panel 120.

[0046] like Figure 1 As shown in , the lifting assembly 200 is disposed below the detection assembly 100 and is fixedly connected thereto, and is used to retract the moving assembly 300, maintain the stability of the detection assembly 100, and prevent the detection process from being disturbed. Figure 2As shown in , the lifting assembly 200 mainly includes a housing 210 and a screw 230, a transmission rod 250, a lifting plate 260 and other components inside the housing 210. Among them, the housing 210 is not only a rectangular shell of the lifting assembly 200, but also a fixed base as the detection assembly 100. Its upper surface is fixedly connected to the detection assembly 100, and its outer bottom wall covers the entire bottom wall and is provided with an anti-slip pad. The right side wall of the housing 210 is fixedly connected to a rectangular protective cover 221, and a motor 220 providing lifting power is provided in the protective cover 221. The motor 220 is electrically connected to the detection assembly 100 and controlled by the operation panel 120. In the housing 210, the screw 230 is horizontally embedded between the left and right side walls of the housing 210, and is rotatably connected to the left and right walls through bearings, and its right end extends out of the right side wall of the housing 210 and is fixedly connected to the output end of the motor 220, and is controlled to rotate by the motor 220. At the same time, a rectangular parallelepiped slider 240 is sleeved on the circumferential side wall of the screw rod 230. The slider 240 has an internal threaded hole in the middle, which is threadedly connected to the screw rod 230. The upper end of the slider 240 is engaged in the upper slide groove 211 set on the top wall of the housing 210, and can only move left and right along the slide groove 211 when the screw rod 230 rotates. One end of the transmission rod 250 is hinged to the lower end of the slider 240 through a hinge axis, and the other end is also hinged to the lower connection block 261 through a hinge axis. The connection block 261 is fixedly embedded on the upper surface of the lifting plate 260. The lifting plate 260 is horizontally arranged and engaged in the side slide grooves 212 set on the left and right side walls of the housing 210. Therefore, when the slider 240 moves left and right, it drives the middle transmission rod 250 to rotate along the upper hinge axis, and the lower lifting plate 260 is lifted up, otherwise it is lowered.

[0047] like Figure 1 As shown in FIG. 1 , the mobile assembly 300 of this embodiment is four universal wheels, which can be extended downward from the extension opening 213 at the bottom of the housing 210 to facilitate the movement of the infrared spectrophotometer of this embodiment. Figure 2 As shown in the figure, the moving assembly 300 is fixedly connected to the lower surface of the lifting plate 260 through the fixed shaft 310 above the universal wheel, near the four corners, and the extension port 213 is also set at the corresponding position of the bottom of the housing 210. Therefore, the moving assembly 300 is raised and lowered synchronously with the lifting plate 260. When lowered, it is used to move the oil tester; when raised, it ensures the stability of the oil tester during detection.

[0048] A specific implementation of this embodiment is as follows: the user first controls the motor on the operation panel 120, through the transmission inside the lifting assembly 200, that is, the motor 220 controls the screw rod 230 to rotate, and when the screw rod 230 rotates, it drives the slider 240 to translate to the left along the slide groove 211, and the slider 240 then drives the middle transmission rod 250 to rotate downward along the hinge axis at the upper end, and the lower lifting plate 260 is pressed down to extend the lower mobile assembly 300, and then the user can easily push the infrared spectrophotometer of this embodiment to move it to the detection position. After reaching the detection position, the user controls the motor again, through the transmission inside the lifting assembly 200, the lower mobile assembly 300 is retracted, and the bottom of the housing 210 is placed stably on the bottom surface. Then, the target detection object is sampled and placed in a test tube, and then the test tube is placed inside the detection port 110 on the detection assembly 100, and the operation panel 120 is operated to start the detection assembly 100 to obtain the detection result. When retesting is required, you can directly take samples for testing again; when you need to change the testing location, just repeat the above steps. The whole process is convenient, fast, time-saving and labor-saving.

[0049] In this embodiment, the infrared spectrophotometer oil meter is provided with a lifting assembly 200 fixedly connected to the detection assembly 100, and a moving assembly 300 is provided under the lifting assembly 200 and is lifted and lowered under the lifting assembly 200, so that the oil meter can be stably supported by the lifting assembly 200 during detection and conveniently moved by the moving assembly 300 during position change, thereby solving the problem in the prior art that the infrared spectrophotometer oil meter as a field detection equipment cannot be conveniently moved, resulting in low efficiency of environmental monitoring work.

[0050] At the same time, in this embodiment, a universal wheel is selected as the moving component 300. By relying on the convenience of changing the moving direction of the universal wheel, the infrared spectrophotometer can adapt to road conditions in different detection environments, thereby enhancing the practicality of the infrared spectrophotometer.

[0051] Preferably, in this embodiment, in order to further improve the stability of the internal structure of the device, two parallel screws 230 and two transmission rods 250 can be set in the lifting assembly 200, and two sliders 240, two motors 220, and two connecting blocks 261 can be set in cooperation. The connection method of the two sets of components remains unchanged and they are arranged symmetrically in the shell 210, thereby maintaining the balance of the lifting plate 260 and making the internal structure of the device more stable.

[0052] Preferably, if Figure 2As shown, in this embodiment, in order to prevent the lifting plate 260 from getting stuck, two left-right symmetrical spring hydraulic rods 270 can also be set on the inner bottom wall of the shell 210. The lower ends of the two spring hydraulic rods 270 are fixedly connected to the inner bottom wall of the shell 210, and the upper ends are fixedly connected to the lower surface of the lifting plate 260. When the moving assembly 300 is retracted, the spring hydraulic rod 270 can push the lifting plate 260 upward to make it move more smoothly, avoiding getting stuck and causing the lifting assembly 200 to fail; at the same time, the spring hydraulic rod 270 supports the lifting plate 260 when it is in the retracted state, dispersing the internal stress of the upper structure and reducing the deformation failure tendency of the upper structure. It should be pointed out that in this embodiment, one, three, four, etc. spring hydraulic rods 270 can be set on the inner bottom wall of the shell 210, and it is better to be evenly distributed on the bottom wall. When only one is set, it is better to set it in the center of the bottom wall.

[0053] Preferably, if Figure 2 As shown in , in this embodiment, in order to prevent the lifting plate 260 from being misplaced, two left-right symmetrical limit rods 280 may be provided on the left and right side walls of the housing 210. Since the side slide grooves 212 are generally shallow, the lifting plate 260 is easily lifted excessively during the lifting process, and is dislocated from the side slide grooves 212. Therefore, the limit rods 280 are provided above the side slide grooves 212 on both sides to prevent the occurrence of misplacement and improve the safety of the lifting device.

[0054] However, in actual testing, sometimes the road conditions at the monitoring point are rugged. In the above embodiment, although the infrared spectrophotometer is easy to move, it is easily affected by complex road conditions during movement, causing the device to be bumpy and the internal precision structure to be damaged, resulting in a reduced service life of the device. In order to further solve these problems on the basis of the first embodiment, a second embodiment is provided below.

[0055] See also Figure 1-3 In the second embodiment, the structure of the moving assembly 300 is mainly changed, and a shock absorbing mechanism 332 is added therein to reduce the vibration of the upper detection assembly 100 and the lifting assembly 200 during the movement.

[0056] like Figure 2 As shown in the figure, the external shape and structure of the moving assembly 300 are similar to those of an ordinary universal wheel, and mainly consist of a fixed shaft 310 fixedly connected to the lower surface of the lifting plate 260, a rotating bracket 320 rotatably connected below the fixed shaft 310, and a caster 330 rotatably connected below the rotating bracket via a rolling shaft 340. The caster 330 is provided with a tire 331 on the outside and a shock absorbing mechanism 332 improved to adapt to complex road conditions inside. Figure 3As shown in the figure, the shock absorbing mechanism 332 mainly includes a fixed plate 3331, a damping spring rod 3332 and a mounting ring 3334. The fixed plate 3331 is sleeved on the rolling shaft 340 and fixedly connected thereto. The mounting ring 3334 is embedded in the tire 331 and detachably connected thereto. The damping spring rod 3332 is radially arranged on the outside of the fixed plate 3331, and the other end is connected to the inside of the mounting ring 3334, which is used to absorb the vibration of the tire and reduce the transmission of the vibration upward, thereby achieving a shock absorbing effect.

[0057] In addition, since the caster 330 is generally small, in complex terrain conditions, the collision and vibration it receives will not only come from the bottom, for example, a larger stone may hit it from the front or oblique front. If the two ends of the damping spring rod 3332 are fixedly connected and arranged along the radial direction of the caster 330, the shock absorption effect is poor and the caster 330 is easily damaged. In view of this problem, in this embodiment, a hexagonal star-shaped fixed plate 3331 is specially designed, and each corner is set to be inclined. At the same time, each damping spring rod 3332 is set to be inclined, and its two ends are set to be hinged with the fixed plate 3331 and the mounting ring 3334. When in use, the front and rear collisions or bottom collisions received by the caster can have a good shock absorption effect, which improves the practicality of the infrared spectrophotometer of this embodiment.

[0058] In the second embodiment, the infrared spectrophotometer absorbs the multi-directional vibrations of the tire by setting a special shock-absorbing mechanism 332 inside the caster 330, reduces the transmission of vibrations upward, and achieves a shock-absorbing effect. This solves the problem that the infrared spectrophotometer in the above embodiment is easily affected by complex road conditions during movement, causing the device to shake, the internal precision structure to be damaged, and the service life of the device to be reduced.

[0059] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
