Description

Technical Field

[0001] The present invention relates to the technical field of wastewater detection, and more particularly to industrial wastewater content testing equipment. Background Art

[0002] Phenol is a moderately toxic substance that poses a risk to humans and other animals. It can enter the human body through the respiratory tract, skin, mucous membranes, and digestive tract, making it a highly toxic substance. Phenol is highly corrosive to human tissue, and contact with eyes can cause severe burns and even blindness. Skin contact not only causes severe burns but can also rapidly enter the body through damaged skin and mucous membranes, leading to systemic poisoning and acute renal failure, acute liver damage, and myocardial damage. Research reports indicate that fish will have a distinctive phenol odor when phenol concentrations in water are 0.1-0.2 mg / L. Concentrations reaching 2.56 mg / L can cause fish poisoning and death. Phenol has been tested for mutagenicity, carcinogenicity, and reproductive toxicity, all within the specified thresholds. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer (IARC) listed phenol as a Class 3 carcinogen.

[0003] In the prior art, commonly used methods for detecting phenol include titration, gas chromatography, gas chromatography + liquid chromatography, gas chromatography-mass spectrometry, and the like.

[0004] However, the above-mentioned methods are all offline detection, which has shortcomings in timeliness and certain requirements for wastewater sampling, transportation and storage of wastewater samples, which affects the detection efficiency and accuracy.

[0010] By adopting the above technical solution, since the two driving modules are symmetrically distributed, the sector teeth in the two driving modules mesh with each other and achieve an effective transmission effect; when the driving motor runs and drives the corresponding sector teeth to make a circumferential rotational motion with the connecting shaft as the axis, the other meshing sector teeth makes the same upward or downward rotational motion, and drives the driving swing arm to make the same rotational motion when the sector teeth rotate, so as to effectively drive the lifting test plate to make a linear motion in the vertical direction when the driving swing arm drives the connecting swing arm to rise or fall; and when the lower ends of the two sector teeth mesh with each other, the lifting test plate is at the highest point; when the upper ends of the two sector teeth mesh with each other, the lifting test plate is at the lowest point, thereby significantly improving the operating stability, efficiency and convenience of the lifting test plate.

[0012] By adopting the above technical solution, when the lifting test plate makes linear motion in the vertical direction, it drives the two expansion plates connected to the corresponding drive modules to operate at the same time; specifically, the fan-shaped teeth drive the expansion connecting arm to make the same rotational motion as the driving swing arm, and then the two symmetrically distributed expansion connecting arms are gradually moved from the upper end spacing being smaller than the lower end spacing to the upper end spacing being larger than the lower end spacing, and the two expansion plates are made to move away from each other and first rise and then lower in the state of the upper end opening of the closed box accommodating cavity, and as the lifting test plate moves to the highest point, the two expansion plates are respectively located at the two ends of the lifting test plate; at this time, the auxiliary balance arm rotates with the rotation of the expansion connecting arm, and while maintaining a real-time parallel state with the expansion connecting arm, the expansion plate moves in a horizontal state, so that the industrial wastewater content testing equipment has the effects of portability, high efficiency and high reliability.

[0013] The present invention is further configured as follows: a lifting hinge plate is provided on the lower side of the lifting test plate, and the connecting swing arm is connected to the lifting hinge plate for up and down rotation; the unfolding connecting arm is used to drive the corresponding unfolding plate to move along the length direction of the lifting test plate, and a bottom groove matching the width of the lifting test plate is provided on the lower side of the unfolding plate, and chamfers are provided on the upper sides of both ends of the lifting test plate along the length direction.

[0014] By adopting the above technical solution, the connection between the lifting hinge plate and the connecting swing arm will significantly reduce the driving difficulty of the lifting test plate and improve its movement stability.

[0016] By adopting the above technical solution, when the lifting test plate moves, the opening and closing drive support plate is made to perform circumferential rotational motion with the opening and closing drive post as the axis through the cooperation relationship between the opening and closing drive post and the drive sleeve, so as to drive multiple clamping movable plates to perform linear motion toward or away from the opening and closing drive support plate; wherein, when the lifting test plate moves to the uppermost end, the opening and closing drive post and the drive sleeve are separated from each other, and the clamping movable plate is moved to the point where the distance from the opening and closing drive support plate is the largest and remains fixed relative to the telescopic connecting block; and when the lifting test plate makes an upward linear movement, the opening and closing drive post cooperates with the drive sleeve to make the opening and closing drive post perform relative circumferential motion with the drive sleeve. The simultaneous rotation and vertical lifting movement enables the opening and closing drive support plate to perform circumferential rotational movement while driving the clamping movable plate to perform linear movement away from the opening and closing drive support plate; correspondingly, when the lifting test plate performs downward linear movement, the opening and closing drive column cooperates with the drive sleeve to enable the opening and closing drive column to perform relative circumferential rotation with the drive sleeve and to perform vertical lifting and lowering movement simultaneously, and the rotation direction is opposite to that when the lifting test plate performs upward linear movement, so that the opening and closing drive support plate performs circumferential rotational movement while driving the clamping movable plate to perform linear movement close to the opening and closing drive support plate, so that the industrial wastewater content testing equipment has the effects of being portable, efficient and highly reliable.

[0017] The present invention is further configured as follows: a threaded column is provided at the lower end of the opening and closing drive column, and the inner side of the drive sleeve is provided with a threaded drive section located at the lower end and threadedly connected to the threaded column and a smooth separation section located at the upper end and matching the length of the threaded column.

[0018] By adopting the above technical solution, when the threaded column is matched with the threaded drive section, the opening and closing drive column will simultaneously perform relative circumferential rotation with the drive sleeve and lift and lower in the vertical direction as the lifting test plate moves; and when the threaded column is matched with the smooth separation section, the opening and closing drive column and the drive sleeve are separated from each other, so that the opening and closing drive column can perform circumferential rotation relative to the drive sleeve, thereby making the industrial wastewater content testing equipment have the effects of simple structure, convenient use and high efficiency.

[0019] The present invention is further configured as follows: the lower side of the opening and closing drive support plate is rotatably connected to a plurality of L-shaped drive arms distributed with equal arcs, and one end of the L-shaped drive arm away from the opening and closing drive support plate is rotatably connected to the corresponding clamping movable plate; the telescopic connecting block is plugged with a plurality of telescopic spring columns that are retractable and respectively connected to the corresponding clamping movable plates.

[0020] By adopting the above technical solution, when the opening and closing driving support plate makes circumferential rotational motion, it will drive the corresponding ends of multiple corresponding L-shaped driving arms to move away from the corresponding clamping movable plate, and then pull the clamping movable plate to make linear movement under the limit of the corresponding telescopic spring column, so as to significantly improve the movement stability of the clamping movable plate, and at the same time achieve the effect of stable fixation of the test instrument, equipment and reagents through the telescopic spring column, so that the industrial wastewater content testing equipment has a reliable effect.

[0021] The present invention is further configured as follows: the telescopic connecting block is quadrilateral, and four clamping movable plates are provided and respectively match the corresponding side of the telescopic connecting block; wherein the two symmetrically distributed clamping movable plates are each connected to two symmetrically distributed telescopic spring columns, and the two telescopic spring columns are connected to each other at one end away from the telescopic connecting block, and the bottom of the corresponding clamping movable plate is provided with an adjustment adapter, and the part connected to the two telescopic spring columns is connected to rotate up and down.

[0022] By adopting the above technical solution, four clamping movable plates distributed with equal arcs on one side of the outer periphery of the quadrilateral telescopic connecting block have the effect of effectively clamping and fixing matching instruments, equipment and reagents, and by adjusting the adapter to connect the clamping movable plate and the telescopic spring column, the storage and use effect of the clamping movable plate will be further improved, so that the industrial wastewater content testing equipment has the effects of portability, efficiency and high reliability.

[0023] The present invention is further configured as follows: the lower end of the telescopic connecting block is provided with a switching bearing rotatably connected to the lifting test plate, and the bottom of the switching bearing is provided with a rotating gear passing through the lower end of the rotating socket; the bottom of the lifting test plate is fixedly connected to a mixing motor, and the output end of the mixing motor is provided with a driving gear meshing with the rotating gear.

[0024] By adopting the above technical solution, the adapter bearing serves the purpose of improving the connection stability and rotation stability; and when the mixing motor drives the driving gear to rotate, the rotating gear engaged with the driving gear will make a rotation movement opposite to the rotation direction of the opening and closing driving support plate when the lifting test plate rises, so as to achieve the effect of stably driving the rotation of the clamping moving plate and the opening and closing driving support plate, and make the industrial wastewater content testing equipment portable, efficient and highly reliable.

[0025] The present invention is further configured as follows: two arc-shaped waist grooves with equal arc distribution and the center of the circle coincides with the axis of the rotating gear are provided on the lower side of the rotating gear, and a groove head and a groove tail are provided at both ends of the arc-shaped waist groove respectively; the opening and closing drive part is provided with a matching connecting plate whose upper side is inserted into the arc-shaped waist groove and moves.

[0026] By adopting the above technical solution, when the lifting test plate moves from bottom to top and performs circumferential rotational motion, the matching connecting plate on the opening and closing drive part moves from the tail end of the arc waist groove to the head end of the groove, and then when the mixing motor drives the telescopic connecting block to perform a rotational motion in the opposite direction to the rotation direction of the opening and closing drive support plate when the lifting test plate rises, the rotating gear abuts against the matching connecting plate through the groove head to drive the opening and closing drive column and the opening and closing drive support plate to perform the same rotational motion, so that the opening and closing drive support plate and the telescopic connecting block remain relatively stationary during the circumferential rotational motion, thereby achieving the purpose of stabilizing the mixing of the test sample, making the industrial wastewater content testing equipment portable, efficient and highly reliable.

[0027] In summary, the present invention has the following beneficial effects: while the vertical linear motion of the lifting test plate is driven by the driving motor, the two unfolding plates are driven to move, so that when the lifting test plate moves to the highest end, the two unfolding plates are respectively located at the two ends of the lifting test plate along the length direction, and when the lifting test plate moves to the lowest end, the two unfolding plates close the upper end opening of the box accommodating cavity; at the same time, during the movement of the lifting test plate, the purpose of making the opening and closing drive support plate perform circumferential rotational motion is achieved by opening and closing the opening and closing drive column at the lower end of the opening and closing drive support plate and the drive sleeve sleeved on the opening and closing drive column, thereby realizing the L-shaped drive arm connected to the clamping movable plate. The driving clamping movable plate has the effect of moving horizontally linearly; and when the lifting test plate moves to the uppermost end, the clamping movable plate moves to the position with the largest distance from the opening and closing driving support plate, so as to achieve an effective clamping effect on the test sample, and then the telescopic connecting block is driven to rotate by the mixing motor, and the telescopic connecting block drives the abutting matching connecting plate to perform the same rotational movement to achieve efficient mixing of the test sample; and when the lifting test plate moves downward, the four clamping movable plates move closer to each other and facilitate the stabilization of the storage box to improve the space utilization rate of the box body, so that the industrial wastewater content testing equipment has the effects of portability, efficiency and high reliability.

[0034] To make the technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] like Figure 1 As shown, an industrial wastewater content testing device includes a portable device housing 1. The portable device housing 1 has a portable function, so it is suitable for being carried out to effectively test the phenol content in industrial wastewater in a timely manner.

[0036] like Figure 1 、 Figure 2 As shown, the portable device case 1 is provided with a case accommodating cavity 11 with an upper opening and a drawer and / or an opening and closing window for opening from the side to connect to the same accommodating cavity, so as to efficiently place and fix the instruments, equipment and reagents to be used for phenol content testing in the case accommodating cavity 11.

[0037] When testing the content of phenol in wastewater, it should be noted that the instruments and equipment are a basic burette, a conical flask and an analytical balance, and the reagents are a bromine standard solution, a sodium thiosulfate standard solution, a starch indicator solution, potassium iodide, hydrochloric acid and trichloroethane.

[0047] It is worth noting that a lifting test plate 2 is disposed within the housing chamber 11 and is configured to perform reciprocating lifting and lowering motion along the height of the housing chamber 11. A mixing and clamping mechanism is plugged into the lifting test plate 2. The portable device housing 1 is equipped with a lifting drive mechanism for driving the lifting test plate 2 upward to open the mixing and clamping mechanism, or for driving the lifting test plate 2 downward to close the mixing and clamping mechanism. Therefore, by embedding the upgraded test plate in the box accommodating cavity 11, the lifting test plate 2 is lifted to the upper end opening of the box accommodating cavity 11 by the lifting drive mechanism when the industrial wastewater content testing equipment is used, thereby significantly improving the space utilization rate, thereby improving the portability of the industrial wastewater content testing equipment; at the same time, the mixing clamping mechanism is opened or folded as the lifting drive mechanism is driven, thereby realizing the opening of the mixing clamping mechanism and achieving the mixing effect of the material when the industrial wastewater content testing equipment is used, and the folding of the mixing clamping mechanism when the lifting test plate 2 is lowered for storage, so that the industrial wastewater content testing equipment has the effects of portability, high efficiency and high reliability.

[0048] It should be noted that if Figure 2 As shown, the lifting drive mechanism includes two drive modules 6 located on one side of the portable device case 1 and symmetrically distributed. Among them, the drive module 6 includes sector teeth 61 for meshing transmission, and the arc surface of the sector teeth 61 in the two drive modules 6 is provided with teeth that mesh with each other, and a connecting shaft 611 is provided at the center of the circle of the sector teeth 61, and the sector teeth 61 make an up and down swinging motion with the axis of the connecting shaft 611 as the rotation axis. At the same time, a driving swing arm 64 that rotates synchronously with the sector teeth 61 is fixedly connected to the connecting shaft 611, and a connecting swing arm 65 is rotatably connected to the end of the driving swing arm 64 away from the connecting shaft 611. The end of the connecting swing arm 65 away from the driving swing arm 64 is connected to the lifting test plate 2 for up and down rotation, and a driving motor 66 for driving rotation is connected to one of the connecting shafts 611. Therefore, due to the symmetrical distribution of the two driving modules 6, the sector teeth 61 in the two driving modules 6 are meshed with each other and achieve an effective transmission effect; when the driving motor 66 runs and drives the corresponding sector teeth 61 to make a circumferential rotational motion with the connecting shaft 611 as the axis, the other meshing sector teeth 61 makes the same upward or downward rotational motion, and drives the driving swing arm 64 to make the same rotational motion when the sector teeth 61 rotates, so as to effectively drive the lifting test plate 2 to make a linear motion in the vertical direction when the driving swing arm 64 drives the connecting swing arm 65 to rise or fall; and when the lower ends of the two sector teeth 61 are meshed with each other, the lifting test plate 2 is at the highest point; when the upper ends of the two sector teeth 61 are meshed with each other, the lifting test plate 2 is at the lowest point, thereby significantly improving the operating stability, efficiency and convenience of the lifting test plate 2.

[0049] like Figure 1 、 Figure 2As shown, two symmetrically distributed rotating plug holes 12 and matching hinge columns 13 are provided on one side of the portable device case 1, and two expansion plates 5 are provided on the upper side of the portable device case 1 for closing the upper end opening of the case accommodating cavity 11 or moving to the symmetrical two sides of the lifting test plate 2 for connection and matching. Among them, the connecting shaft 611 is inserted into the corresponding rotating plug hole 12, and the driving swing arm 64 is located at the end of the connecting shaft 611 inserted into the portable device case 1. The other end of the connecting shaft 611 is fixedly connected to an expansion connecting arm 62 that rotates synchronously with the sector teeth 61, and the upper end of the expansion connecting arm 62 is away from the connecting shaft 611 and is rotationally connected to the corresponding expansion plate 5.

[0050] It should be mentioned that two linked hinged columns 52 are provided on one side of the unfolding plate 5, and one of the linked hinged columns 52 is rotatably connected to the corresponding end of the unfolding connecting arm 62, and the other linked hinged column 52 is rotatably connected to an auxiliary balancing arm 63 which is parallel to the unfolding connecting arm 62 and the other end of which is rotatably connected to the corresponding matching hinged column 13. Therefore, when the lifting test plate 2 makes linear motion in the vertical direction, it drives the two expansion plates 5 connected to the corresponding driving modules 6 to operate at the same time; specifically, the driving of the sector teeth 61 drives the expansion connecting arm 62 to make the same rotational motion as the driving swing arm 64, and then makes the two symmetrically distributed expansion connecting arms 62 gradually move from the upper end spacing being smaller than the lower end spacing to the upper end spacing being larger than the lower end spacing, and makes the two expansion plates 5 move away from each other and first rise and then lower in the state of the upper end opening of the closed box accommodating cavity 11, and as the lifting test plate 2 moves to the highest point, the two expansion plates 5 are respectively located at the two ends of the lifting test plate 2; at this time, the auxiliary balance arm 63 rotates with the rotation of the expansion connecting arm 62, and while maintaining a real-time parallel state with the expansion connecting arm 62, makes the expansion plate 5 move in a horizontal state, so that the industrial wastewater content testing equipment has the effects of portability, high efficiency and high reliability.

[0051] In order to further improve the ease of use and stability of the phenol content testing equipment for the industry's wastewater, a lifting hinge plate 21 is provided on the lower side of the lifting test plate 2. The connecting swing arm 65 is connected to the lifting hinge plate 21 for rotation up and down, so as to achieve the movement of the lifting test plate 2 while driving the lifting hinge plate 21. The unfolding connecting arm 62 is used to drive the corresponding unfolding plate 5 to move along the length direction of the lifting test plate 2, and the lower side of the unfolding plate 5 is provided with a bottom groove 51 that matches the width of the lifting test plate 2, so as to avoid affecting the lifting test plate 2 from performing the upgrading movement in the vertical direction. At the same time, chamfers 22 are provided on the upper side of both ends of the lifting test plate 2 along the length direction. Therefore, the connection between the lifting hinge plate 21 and the connecting swing arm 65 will significantly reduce the driving difficulty of the lifting test plate 2 and improve its movement stability, and the unfolding connecting arm 62 drives the unfolding plate 5 to move along the length direction of the lifting test plate 2 and move to the two ends of the length direction of the lifting test plate 2, so that the upper side of the industrial wastewater content testing equipment has a space convenient for testing, so as to facilitate the placement of instruments, equipment and reagents; and by setting a chamfer 22 on the lifting test plate 2 to improve the movement stability of the unfolding plate 5 and the coordination effect with the lifting test plate 2.

[0052] like Figure 3 、 Figure 4 As shown, the mixing and clamping mechanism includes a telescopic connecting block 3, an opening and closing drive support plate 4 located above the telescopic connecting block 3, and a plurality of clamping movable plates 33 with equal arcs distributed outside the opening and closing drive support plate 4. The clamping movable plates 33 are used to clamp and secure instruments, equipment, and reagents. The inner side of the clamping movable plates 33 is curved and is used to cooperate with and secure corresponding Erlenmeyer flasks. The opening and closing drive support plate 4 is used to drive the clamping movable plates 33 to move horizontally and linearly, and the telescopic connecting block 3 is used to limit the horizontal linear movement of the clamping movable plates 33.

[0053] Specifically, a rotation socket 23 is provided at the center of the lifting test plate 2, and the lower side of the telescopic connecting block 3 is inserted into the rotation socket 23 and is rotationally connected to the lifting test plate 2. An opening and closing drive column 41 is provided on the lower side of the opening and closing drive support plate 4. It vertically penetrates the telescopic connecting block 3 and is inserted into the box accommodating cavity 11. A drive sleeve 42, which is fixedly connected to the portable device box 1, is sleeved on the opening and closing drive column 41.

[0054] During the operation of the lifting side plate, when the lifting test plate 2 rises or falls in the vertical direction, the opening and closing drive column 41 makes a relative circumferential rotation with the drive sleeve 42 and moves up and down in the vertical direction at the same time, and drives multiple clamping movable plates 33 to make linear motion toward or away from the closing drive support plate 4, and when the lifting test plate 2 is at the uppermost end, the opening and closing drive column 41 and the drive sleeve 42 are separated from each other. Therefore, when the lifting test plate 2 moves, the opening and closing drive support plate 4 is made to rotate circumferentially with the opening and closing drive column 41 as the axis through the cooperation relationship between the opening and closing drive column 41 and the drive sleeve 42, so as to drive the multiple clamping movable plates 33 to make linear movements toward or away from the opening and closing drive support plate 4; wherein, when the lifting test plate 2 moves to the uppermost end, the opening and closing drive column 41 and the drive sleeve 42 are separated from each other, and the clamping movable plate 33 is moved to the point where the distance from the opening and closing drive support plate 4 is the largest and remains fixed relative to the telescopic connecting block 3; and when the lifting test plate 2 makes an upward linear movement, the opening and closing drive column 41 cooperates with the drive sleeve 42 to make the opening and closing drive column 41 relative to the drive sleeve 42 The circumferential rotation and the vertical lifting movement are performed simultaneously, so that the opening and closing drive support plate 4 performs the circumferential rotation movement and drives the clamping movable plate 33 to perform the linear movement away from the opening and closing drive support plate 4; correspondingly, when the lifting test plate 2 performs the downward linear movement, the opening and closing drive column 41 cooperates with the drive sleeve 42 and realizes that the opening and closing drive column 41 performs the relative circumferential rotation with the drive sleeve 42 and the vertical lifting movement, and the rotation direction is opposite to that when the lifting test plate 2 performs the upward linear movement, so that the opening and closing drive support plate 4 performs the circumferential rotation movement and drives the clamping movable plate 33 to perform the linear movement close to the opening and closing drive support plate 4, so that the industrial wastewater content testing equipment has the effects of portability, high efficiency and high reliability.

[0055] It should be mentioned that a threaded column 411 is provided at the lower end of the opening and closing drive column 41. A threaded drive section 421 located at the lower end and threadedly connected to the threaded column 411 and a smooth separation section 422 located at the upper end and matching the length of the threaded column 411 are provided on the inner side of the drive sleeve 42. When the threaded column 411 is matched with the threaded drive section 421, the opening and closing drive column 41 will simultaneously rotate relative to the drive sleeve 42 in the circumferential direction and move up and down in the vertical direction as the lifting test plate 2 moves. When the threaded column 411 is matched with the smooth separation section 422, the opening and closing drive column 41 and the drive sleeve 42 are separated from each other, so that the opening and closing drive column 41 can rotate relative to the drive sleeve 42 in the circumferential direction. This will make the industrial wastewater content testing equipment simple in structure, easy to use and efficient.

[0056] like Figure 4As shown, a plurality of L-shaped drive arms 43, distributed at equal arcs, are rotatably connected to the underside of the opening and closing drive support plate 4. One end of the L-shaped drive arm 43, which is away from the opening and closing drive support plate 4, is rotatably connected to the corresponding clamping movable plate 33. Multiple retractable telescopic spring columns 34, each connected to a corresponding clamping movable plate 33, are plugged into the telescopic connection block 3. This stabilizes the clamping movable plate 33 while restricting the clamping movable plate 33 to horizontal linear movement. Specifically, when the opening and closing drive support plate 4 rotates circumferentially, the opening and closing drive support plate 4 drives the corresponding ends of the L-shaped drive arms 43 to move away from the corresponding clamping movable plate 33, thereby pulling the clamping movable plate 33 to move linearly within the limits of the corresponding telescopic spring columns 34. This significantly improves the stability of the clamping movable plate 33 while also providing a stable fixation of the test instrument, equipment, and reagents through the telescopic spring columns 34, thereby ensuring the reliability of the industrial wastewater content test equipment.

[0057] like Figure 3 、 Figure 4 As shown, the telescopic connecting block 3 is quadrilateral, and four clamping movable plates 33 are provided, each matching a corresponding side of the telescopic connecting block 3. Two symmetrically distributed clamping movable plates 33 are each connected to two symmetrically distributed telescopic spring columns 34, and the two telescopic spring columns 34 are interconnected at one end away from the telescopic connecting block 3. An adjustment adapter 331 is provided at the bottom of each clamping movable plate 33, and the portion connected to the two telescopic spring columns 34 is connected for vertical rotation. The other two symmetrically distributed clamping movable plates 33 are each connected to one or two telescopic spring columns 34. When connected to a telescopic spring column 34, the corresponding clamping movable plate 33 is rotationally connected to the corresponding telescopic spring column 34 and is configured to perform circumferential rotational motion about the corresponding telescopic spring column 34. Therefore, the four clamping movable plates 33 distributed with equal arcs on one side of the outer periphery of the quadrilateral telescopic connecting block 3 have the effect of effectively clamping and fixing matching instruments, equipment and reagents, and by adjusting the adapter 331 to connect the clamping movable plate 33 and the telescopic spring column 34, the storage and use effect of the clamping movable plate 33 will be further improved, so that the industrial wastewater content testing equipment has the effects of portability, efficiency and high reliability.

[0058] like Figure 4 、 Figure 5As shown, a transfer bearing 32 is provided at the lower end of the telescopic connection block 3 for rotationally connecting to the lifting test plate 2, and a rotating gear 321 is provided at the bottom of the transfer bearing 32, extending from the lower end of the rotating socket 23. Correspondingly, a mixing motor 31 is fixedly connected to the bottom of the lifting test plate 2, and a drive gear 311 is provided at the output end of the mixing motor 31, which engages with the rotating gear 321. Therefore, the transfer bearing 32 serves to improve connection stability and rotational stability. When the mixing motor 31 drives the drive gear 311 to rotate, the rotating gear 321, which engages with the drive gear 311, rotates in the opposite direction to the rotation of the opening and closing drive support plate 4 when the lifting test plate 2 rises, thereby achieving a stable rotation effect of driving the clamping movable plate 33 and the opening and closing drive support plate 4, and making the industrial wastewater content testing equipment portable, efficient, and highly reliable. It should be noted that in order to enable the telescopic connecting block 3 to drive the opening and closing drive support plate 4 to perform the same circumferential rotational motion as it performs circumferential rotational motion, two arcuate waist grooves 3211 with equal arc distribution and the center of the circle coinciding with the axis of the rotating gear 321 are provided on the lower side of the rotating gear 321. The two ends of the arcuate waist groove 3211 are respectively provided with a groove head 3212 and a groove tail 3213, and the opening and closing drive unit is provided with a matching connecting plate 412 that is inserted and moved within the arcuate waist groove 3211. The matching connecting plate 412 is connected by setting a plug column to be inserted into the arc waist groove 3211, so that when the lifting test plate 2 moves from bottom to top and performs a circumferential rotational motion, the matching connecting plate 412 on the opening and closing drive part moves from the groove tail 3213 of the arc waist groove 3211 to the groove head 3212, and then when the mixing motor 31 drives the telescopic connecting block 3 to perform a rotational motion in the opposite direction to the rotation direction of the opening and closing drive support plate 4 when the lifting test plate 2 rises, the rotating gear 321 abuts against the matching connecting plate 412 through the groove head 3212 to drive the opening and closing drive column 41 and the opening and closing drive support plate 4 to perform the same rotational motion, so that the opening and closing drive support plate 4 and the telescopic connecting block 3 remain relatively stationary during the circumferential rotational motion, thereby achieving the purpose of stabilizing the mixing of the test sample, making the industrial wastewater content testing equipment portable, efficient and highly reliable.

[0059] In summary, the present application drives the vertical linear movement of the lifting test plate 2 by the driving motor 66, and drives the two unfolding plates 5 to move, so that when the lifting test plate 2 moves to the highest end, the two unfolding plates 5 are respectively located at the two ends of the lifting test plate 2 along the length direction, and when the lifting test plate 2 moves to the lowest end, the two unfolding plates 5 close the upper end opening of the box accommodating cavity 11; at the same time, during the movement of the lifting test plate 2, the purpose of making the opening and closing drive support plate 4 perform circumferential rotational movement is achieved by opening and closing the opening and closing drive column 41 at the lower end of the support plate 4 and the drive sleeve 42 sleeved on the opening and closing drive column 41, thereby achieving driving through the L-shaped drive arm 43 connected to the clamping movable plate 33. The clamping movable plate 33 has the effect of moving horizontally linearly; and when the lifting test plate 2 moves to the uppermost end, the clamping movable plate 33 moves to the position with the largest distance from the opening and closing drive support plate 4, so as to achieve an effective clamping effect on the test sample, and then the telescopic connecting block 3 is driven to rotate by the mixing motor 31, and the telescopic connecting block 3 drives the abutting matching connecting plate 412 to perform the same rotational movement to achieve efficient mixing of the test sample; and when the lifting test plate 2 moves downward, the four clamping movable plates 33 move closer to each other and facilitate the purpose of stabilizing the storage box and improving the space utilization rate of the box accommodating cavity 11, so that the industrial wastewater content testing equipment has the effects of being portable, efficient and highly reliable.
