Description

Technical Field

[0001] This utility model relates to the field of wastewater detection technology, and in particular to a detection device for desulfurization wastewater from thermal power plants. Background Technology

[0002] Thermal power plants primarily generate electricity by burning fossil fuels such as coal. Coal contains a certain amount of sulfur, which reacts with oxygen during combustion to produce sulfur dioxide, which is emitted into the atmosphere along with the flue gas. To reduce sulfur dioxide pollution, thermal power plants typically employ flue gas desulfurization (FGD) technology. This complex chemical absorption and oxidation process generates a large amount of desulfurization wastewater containing various impurities, including heavy metal ions. These heavy metals mainly originate from trace amounts of heavy metals naturally present in coal. During desulfurization, they enter the wastewater through chemical reactions. Detection devices can promptly identify changes in the concentration of these substances, allowing staff to take appropriate anti-scaling measures, such as adding scale inhibitors or adjusting the dosage of chemical agents, to ensure the stable operation of the desulfurization system. However, the accuracy of existing detection probes decreases after prolonged use, necessitating replacement, and the overall design of the detection devices makes them inconvenient to replace via the wastewater pipes.

[0003] Therefore, there is an urgent need to provide a detection device for desulfurization wastewater from thermal power plants to solve the above problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that the detection device in the overall structure is not convenient to replace from the sewage pipe.

[0005] To solve the above-mentioned technical problems, the present invention provides a detection device for desulfurization wastewater from thermal power plants, comprising a wastewater pipe, an insertion groove on the wastewater pipe, a detection box slidably connected in the insertion groove, and a positioning mechanism on one side of the detection box; the positioning mechanism includes a fixed connecting shaft fixedly connected to one side of the detection box, a first connecting shaft and a second connecting shaft rotatably connected to both ends of the fixed connecting shaft, the first connecting shaft being fixedly connected to a second limiting arm, the second connecting shaft being fixedly connected to the first limiting arm, an mounting platform being fixedly installed on the upper end of the fixed connecting shaft, and a drive opening and closing mechanism being provided on one side of the positioning mechanism.

[0006] The present invention is further configured such that: the driving opening and closing mechanism includes a limiting shaft fixed to the upper surface of the mounting platform, the outer wall of the limiting shaft is rotatably connected to a first mounting cylinder and a second mounting cylinder, the outer wall of the limiting shaft is also equipped with a torsion spring corresponding to the first mounting cylinder and the second mounting cylinder, and a left rotating arm and a right rotating arm are fixedly connected to one end of the first mounting cylinder and the second mounting cylinder, respectively.

[0007] Through the above technical solution, the outer wall of the limiting shaft is equipped with a torsion spring corresponding to the first mounting cylinder and the second mounting cylinder. Under the elastic action of the torsion spring, the left and right rotating arms can be automatically reset, which in turn can drive the first limiting arm and the second limiting arm to automatically close the mold.

[0008] The present invention is further configured such that: two drive gears are rotatably connected to the upper end of the mounting platform; a mounting winch is fixedly connected to the central shaft of each of the two drive gears; steel ropes are wound around the outer walls of both mounting winches; a ratchet is rotatably mounted on the inner wall of the mounting platform; the ratchet is fixedly connected to one of the drive gears; and a drive disc is fixedly connected to the center of the ratchet.

[0009] The present invention is further configured such that the two driving gears mesh and drive each other, and a handle is fixedly installed on the drive disc.

[0010] The present invention is further configured such that: a fixing rod is fixedly connected to the front end of the bottom of the left rotating arm and the right rotating arm, and a steel rope is fixedly connected to one side of the fixing rod, and the other ends of the two steel ropes are respectively wound around the installation winch for fixation.

[0011] With the above technical solution, the drive gear at the top of the mounting platform rotates while meshing with the drive gear on the other side, which in turn drives the two installation winches to rotate synchronously, allowing the two steel cables to be released slowly.

[0012] The present invention is further configured such that: a limiting head is provided on one side of the ratchet, a movable column is fixedly connected to the end of the limiting head away from the ratchet, the movable column is slidably connected to the mounting platform, and a spring is sleeved on the movable column.

[0013] With the above technical solution, when the drive disc stops rotating, the moving column is released, and the spring pushes the limit head to slide towards the ratchet, so that the limit head is inserted into the ratchet, thereby fixing the position of the ratchet and preventing it from rotating on its own.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes a design that combines a drive opening / closing mechanism with a positioning mechanism. When the operator rotates the drive disc, the rotation of the drive disc drives the drive gears to rotate. Because the two drive gears mesh with each other, the two mounting winches can rotate synchronously, which in turn drives the two steel ropes to continuously wind or release, causing the first and second limit arms to open or close, thereby fixing the position of the detection box. When the detection box needs to be replaced, the operator does not need to use complicated tools for disassembly and installation, ensuring that the detection box can quickly be in the correct detection position after each installation, resulting in higher efficiency.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] Please see Figures 1-4 A detection device for desulfurization wastewater from a thermal power plant includes a wastewater pipe 1 with an insertion groove 11. A detection box 2 is slidably connected in the insertion groove 11. A positioning mechanism 3 is provided on one side of the detection box 2. The positioning mechanism 3 includes a fixed connecting shaft 31 fixedly connected to one side of the detection box 2. A first connecting shaft 34 and a second connecting shaft 35 are rotatably connected to both ends of the fixed connecting shaft 31. The first connecting shaft 34 is fixedly connected to a second limiting arm 33, and the second connecting shaft 35 is fixedly connected to a first limiting arm 32. An installation platform 36 is fixedly installed on the upper end of the fixed connecting shaft 31. A drive opening and closing mechanism 4 is provided on one side of the positioning mechanism 3.

[0023] The drive opening and closing mechanism 4 includes a limiting shaft 40 fixed to the upper surface of the mounting platform 36. The outer wall of the limiting shaft 40 is rotatably connected to a first mounting cylinder 41 and a second mounting cylinder 42. The outer wall of the limiting shaft 40 is also equipped with torsion springs 43 corresponding to the first mounting cylinder 41 and the second mounting cylinder 42. One end of the first mounting cylinder 41 and the second mounting cylinder 42 is fixedly connected to a left rotating arm 44 and a right rotating arm 45, respectively. The outer wall of the limiting shaft 40 is equipped with torsion springs 43 corresponding to the first mounting cylinder 41 and the second mounting cylinder 42. Under the elastic action of the torsion springs 43, the left rotating arm 44 and the right rotating arm 45 can be driven to automatically reset, thereby driving the first limiting arm 32 and the second limiting arm 33 to automatically close the mold.

[0024] Two drive gears 49 are rotatably connected to the upper end of the mounting platform 36. A mounting winch 48 is fixedly connected to the central shaft of each of the two drive gears 49. Steel ropes 47 are wound around the outer walls of both mounting winches 48. A ratchet 410 is rotatably mounted on the inner wall of the mounting platform 36. The ratchet 410 is fixedly connected to one of the drive gears 49. A drive disc 411 is fixedly connected to the center of the ratchet 410.

[0025] The two drive gears 49 mesh with each other, and a handle is fixedly installed on the drive disc 411.

[0026] The front ends of the bottom of the left rotating arm 44 and the right rotating arm 45 are fixedly connected to a fixing rod 46. A steel rope 47 is fixedly connected to one side of the fixing rod 46. The other ends of the two steel ropes 47 are respectively wound around the installation winch 48 and fixed. When the drive gear 49 at the top of the mounting platform 36 rotates, it drives the drive gear 49 on the other side to rotate through meshing, which in turn drives the two installation winches 48 to rotate synchronously, so that the two steel ropes 47 are slowly released.

[0027] A limiting head 413 is provided on one side of the ratchet 410. A movable column 412 is fixedly connected to the end of the limiting head 413 away from the ratchet 410. The movable column 412 is slidably connected to the mounting platform 36. A spring 414 is sleeved on the movable column 412. When the drive disk 411 stops rotating, the movable column 412 is released, and the spring 414 pushes the limiting head 413 to slide towards the ratchet 410, so that the limiting head 413 is inserted into the ratchet 410, thereby fixing the position of the ratchet 410 and preventing it from rotating on its own.

[0028] In use, the first mounting cylinder 41 of the first limiting arm and the second mounting cylinder 42 of the second limiting arm are placed on the outer wall of the wastewater pipe 1. At the same time, the detection box 2 is inserted into the insertion slot 11. By turning the handle, the drive disc 411 is rotated, which drives the ratchet 410 to rotate. The drive gear 49 at the upper end of the mounting platform 36 rotates and drives the drive gear 49 on the other side to rotate through meshing. This drives the two mounting winches 48 to rotate synchronously, so that the two steel ropes 47 are slowly released. The outer wall of the limiting shaft 40 is equipped with torsion springs 43 corresponding to the first mounting cylinder 41 and the second mounting cylinder 42. Under the elastic action of the torsion springs 43, the left rotating arm 44 and the right rotating arm 45 can be automatically reset. This can then drive the first limiting arm 32 and the second limiting arm 33 to automatically close, thereby naturally and vertically fixing the detection box 2 in the wastewater pipe 1 to detect the flowing wastewater.
