Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a multi-parameter water quality analyzer. Background Technology

[0002] Multi-parameter water quality analyzers are professional instruments used to analyze the content of water components. They mainly refer to instruments that measure the following items in water: BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, pH, dissolved oxygen, etc. In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge. Multi-parameter water quality analyzers play an important role in environmental protection, water quality testing, and water resource protection. Among them, the lamp body assembly of the multi-parameter water quality analyzer is one of the core structures for realizing optical water quality parameter testing. It is usually composed of components such as lamp head, pressure cap, lamp holder and bottom cover. The lamp holder needs to integrate LED lamp mounting position, filter mounting position and light detector receiver mounting position. Through the cooperation of corresponding functional components, the emission, filtering and reception of light of specific wavelengths can be realized, thereby completing the detection of water quality indicators.

[0003] The existing lamp assembly is complicated and time-consuming to disassemble and assemble on the measuring instrument. Furthermore, the mounting positions of core functional components such as filters and LEDs are integrated inside the lamp holder, and the lamp assembly is fixed inside the measuring instrument. This makes it inconvenient to replace such components and is also easy to cause bumps and scratches to the lamp holder and functional components during disassembly and assembly, which in turn affects the assembly accuracy of the components and the stability of the test data. Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-parameter water quality analyzer, including a housing, on which an intelligent touch screen and a measuring station are provided, and a lamp mounting slot is provided on the measuring station, on which a lamp assembly is installed; The lamp assembly includes a top cover that is inserted and fixed to the lamp mounting slot, and a lamp cover, lamp holder, and bottom cover located inside the housing. The lamp holder is used to install the lamp source, filter, and light detector receiver. The lamp cover has a slot for inserting reagents. The top cover is provided with ear plates around its perimeter, and a post is provided at the lower end of the ear plate. The measuring station is provided with a slot corresponding to the post, and the post is inserted into the slot from top to bottom. The top cover has two symmetrically arranged L-shaped plates on its upper surface.

[0006] As a further embodiment of this utility model: the measuring station is also provided with a movable groove, the lamp body mounting groove is provided on the movable groove, and a baffle is slidably fitted in the movable groove. The baffle can slide in the movable groove to cover the lamp body assembly in the lamp body mounting groove.

[0007] As a further embodiment of this utility model: a magnetic attractor is embedded in the inner wall of the movable groove, and a magnetically attracted component is embedded in the side of the baffle facing the magnetic attractor. When the baffle slides above the lamp body assembly, the magnetically attracted component and the magnetic attractor attract each other and are fixed in place.

[0008] As a further embodiment of this utility model: the lower end of the baffle is provided with a clearance groove corresponding to the L-shaped plate. When the baffle slides above the lamp body assembly, the L-shaped plate and the clearance groove interlock.

[0009] As a further embodiment of this utility model: the lower end of the top cover is provided with a plurality of screw posts, the lower end of the screw posts is provided with screw holes, the lamp cover, the lamp holder and the bottom cover are provided with a plurality of through holes coaxially, and the lower end of the bottom cover is provided with a screw rod, which passes through the through holes and is screwed and fixed to the screw holes.

[0010] As a further embodiment of this utility model: the upper and lower surfaces of the lamp holder are provided with multiple lamp source mounting positions and multiple light detector receiver mounting positions, the multiple lamp source mounting positions and multiple light detector receiver mounting positions are symmetrically positioned, and the light detector receiver mounting positions are provided with filter mounting slots, wherein the lamp source mounting positions and light detector receiver mounting positions of the same group are on the same axial direction.

[0011] Compared with existing technologies, the advantages of this technical solution are as follows: Workers can grip the top cover using two L-shaped plates, then lift it up, causing the inserts at the lower ends of the ear plates around the top cover to disengage from the slots on the measuring station. This allows the top cover, lamp cover, lamp holder, and bottom cover to be removed from the lamp body mounting slot and the housing, facilitating the maintenance and replacement of internal components and ensuring the accuracy and stability of test data during long-term use. When reinstalling the lamp body assembly, gripping the top cover controls the lamp cover, lamp holder, and bottom cover to pass through the lamp body mounting slot. Once inside the housing, the pins around the top cover engage with the slots on the measuring station to secure the lamp assembly. The assembly and disassembly process is simple and quick. The lamp cover, lamp holder, and bottom cover can be removed first before maintaining or replacing critical components, avoiding any impact. Furthermore, when the instrument is not in use, the baffle can be slid above the lamp assembly to limit its movement and prevent vertical displacement of the lamp assembly during instrument transfer, which could cause misalignment of internal components and affect the accuracy of the test data.

[0015] 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.

[0016] Please see Figure 1-6A multi-parameter water quality analyzer includes a housing 1, on which a smart touch screen 2 and a measuring station 3 are provided. A lamp mounting slot 31 is provided on the measuring station 3, and a lamp assembly 4 is installed on the lamp mounting slot 31. The lamp assembly 4 includes a top cover 41 that is plugged into and fixed to the lamp mounting groove 31, and a lamp cover 42, a lamp holder 43, and a bottom cover 44 located inside the housing 1. The lamp holder 43 is used to install a lamp source, a filter, and a light detector receiver. The lamp cover 42 has a slot 421 for reagents to be placed in. When water quality is measured, water reagents are placed into the lamp holder 43 through the slot 421 on the lamp cover 42. The lamp source, filter, and light detector receiver inside the lamp holder 43 emit, filter, and receive light of a specific wavelength, thereby completing the detection of various water quality indicators. The top cover 41 is provided with ear plates 411 around its perimeter. The lower end of the ear plates 411 is provided with a post 412. The measuring station 3 is provided with a slot 32 corresponding to the post 412. The post 412 is inserted into the slot 32 from top to bottom. The top cover 41 has two symmetrically arranged L-shaped plates 413 on its upper surface.

[0017] When it is necessary to remove the lamp body assembly 4 from the lamp body mounting slot 31 for maintenance or replacement of the internal filter, lamp source, and light detector receiver, the operator can use two L-shaped plates 413 to grip the top cover 41, then lift the top cover 41 so that the inserts 412 at the lower end of the ear plates 411 around the top cover 41 disengage from the slots 32 on the measuring station 3. This allows the top cover 41, lamp cover 42, lamp holder 43, and bottom cover 44 to be removed from the lamp body mounting slot 31 and the housing 1, facilitating the maintenance and replacement of internal components. To ensure the accuracy and stability of test data during long-term use of the instrument, when reinstalling the lamp body assembly 4, grasp the top cover 41 to control the lamp cover 42, lamp holder 43 and bottom cover 44 to pass through the lamp body mounting groove 31 into the housing 1. Then, the inserts 412 around the top cover 41 are inserted into the slots 32 on the measuring station 3 to fix the lamp body assembly 4 to the measuring station 3. The disassembly and assembly steps are simple and time-saving. The lamp cover 42, lamp holder 43 and bottom cover 44 can be removed first before the maintenance and replacement of key components are carried out to avoid bumps and knocks. Preferably, a soft rubber sleeve (not shown in the figure) can be fitted over the outside of the insertion post 412 to achieve an interference fit with the slot 32, thereby improving the firmness of the lamp body assembly 4 after installation and preventing the lamp body assembly 4 from shaking during use.

[0018] Based on the above embodiments, the measuring station 3 is also provided with a movable groove 33, the lamp body mounting groove 31 is provided on the movable groove 33, and a baffle 5 is slidably fitted in the movable groove 33. The baffle 5 can slide in the movable groove 33 to cover the lamp body assembly 4 in the lamp body mounting groove 31.

[0019] Specifically, when the instrument is not in use, the baffle 5 can be slid above the lamp assembly 4 to limit the lamp assembly 4 and prevent the lamp assembly 4 from shifting vertically during the instrument transfer process, which could cause misalignment of internal components and affect the accuracy of the test data. When conducting water quality tests, the baffle 5 can be slid to the other side of the movable trough 33 to expose the lamp assembly 4, so that water reagents can be placed inside.

[0020] Furthermore, a magnetic attractor 34 is embedded in the inner wall of the movable groove 33, and a magnetic attractor 51 is embedded in the side of the baffle 5 facing the magnetic attractor 34. When the baffle 5 slides above the lamp body assembly 4, the magnetic attractor 51 and the magnetic attractor 34 attract and fix each other.

[0021] Specifically, by attracting and fixing the magnetic component 34 (magnet) and the magnetically attracted component 51 (iron block) to each other, the baffle 5 can be prevented from sliding above the lamp body assembly 4 and then shifting on its own, thus preventing the limiting effect on the lamp body assembly 4 from disappearing.

[0022] Furthermore, the lower end of the baffle 5 is provided with a relief groove 52 corresponding to the L-shaped plate 413. When the baffle 5 slides above the lamp body assembly 4, the L-shaped plate 413 and the relief groove 52 interlock and cooperate.

[0023] Specifically, the opening of the clearance groove 52 at the lower end of the baffle 5 can avoid the movement conflict between the baffle 5 and the L-shaped plate 413 during the sliding process, so that after the baffle 5 moves above the lamp body assembly 4, its bottom surface is as close as possible to the top surface of the lamp body assembly 4, ensuring the limiting effect on the lamp body assembly 4.

[0024] Based on the above embodiments, it is further proposed that the lower end of the top cover 41 is provided with a plurality of screw posts 414, the lower end of the screw posts 414 is provided with screw holes 415, the lamp cover 42, the lamp holder 43 and the bottom cover 44 are coaxially provided with a plurality of through holes 6, and the lower end of the bottom cover 44 is provided with a screw rod 7, which passes through the through holes 6 and is screwed and fixed to the screw holes 415.

[0025] Specifically, when assembling the lamp cover 42, lamp holder 43 and bottom cover 44, the three are spliced ​​together and their respective through holes 6 are aligned with each other. The screw post 414 at the lower end of the top cover 41 is inserted into the through hole 6 on the lamp cover 42. Then, the screw 7 is inserted into the through hole 6 and screwed in, so that the screw 7 is screwed into the screw hole 415 inside the screw post 414. After tightening, the top cover 41, lamp cover 42, lamp holder 43 and bottom cover 44 can be fixedly assembled. Preferably, a positioning post and a positioning hole (not shown in the figure) can be provided between the lamp cover 42, the lamp holder 43 and the bottom cover 44 for screwing and fixing the pre-assembly between the lamp cover 42, the lamp holder 43 and the bottom cover 44.

[0026] Based on the above embodiments, it is further proposed that the upper and lower surfaces of the lamp holder 43 are provided with multiple lamp source mounting positions 431 and multiple light detector receiver mounting positions 432. The multiple lamp source mounting positions 431 and multiple light detector receiver mounting positions 432 are symmetrically positioned, and the light detector receiver mounting positions 432 are provided with filter mounting slots 433. The lamp source mounting positions 431 and light detector receiver mounting positions 432 of the same group are on the same axial direction.

[0027] This allows for the setting of light sources with different wavelengths on the lamp holder 43, enabling the simultaneous measurement of multiple water quality parameters when measuring water quality. The light source is specifically an LED lamp.

[0028] Preferably, the wires connected to the light source and the light detector receiver after installation are bundled and organized with cable ties, while leaving enough length so that the wires are not pulled when the light body assembly 4 is removed.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
