Description

Technical Field

[0001] The present invention relates to the technical field of industrial water pollution detection, in particular to an industrial water pollution detection sampler. Background Art

[0002] With the rapid development of industrialization, water pollution is becoming increasingly serious, and the demand for environmental monitoring is growing accordingly. Accurate and efficient water sampling is a key prerequisite for pollution detection, and the performance of the sampler directly affects the reliability of the test data. However, traditional sampling devices have certain limitations in structural design and functional implementation, making it difficult to meet the technical requirements of modern industrial scenarios for rapid, synchronous, and multi-point sampling.

[0003] In order to solve the above problems, the patent document with publication number CN118654949A in the prior art provides an industrial water pollution detection sampler; the device can drive the sampling box to move horizontally through the moving parts, connecting blocks and sliding blocks, and can drive the sampling box to move up and down through the driving parts and connecting blocks, so that the height of the sampling box can be adjusted within the sampling water area, and two upper and lower water inlets are set to sample industrial wastewater of different depths.

[0004] However, the device still has the following problems: the device seals the water inlet by rotating the cover body in conjunction with the rotating motor. Since the rotation process of the cover body takes a long time, it is difficult to achieve instantaneous interception, which may cause water from non-target periods to mix in, affecting the temporal representativeness of the sampling. This is obviously a major defect. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background technology and to propose an industrial water pollution detection sampler.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an industrial water pollution detection sampler, comprising a bracket and a first sampling box and a second sampling box, the first sampling box being connected to the bracket through a wire brush, the second sampling box being plugged into and installed at the lower end of the first sampling box, water inlets being provided on the surfaces of the first sampling box and the second sampling box, a rotating ring being rotatably installed on the inner side of the water inlet, a plurality of sealing blocks being slidably installed between the rotating ring and the water inlet, a driving mechanism and a lifting mechanism being provided on the outer sides of the first sampling box and the second sampling box, the driving mechanism comprising a first motor and two driving rods, the two driving rods being respectively arranged in the first sampling box and the second sampling box, and adjacent driving rods being meshed with the rotating rings.

[0007] In the above-mentioned industrial water pollution detection sampler, a filter screen is clamped and installed in the water inlet, and a first limit slider and a second limit slider are fixedly installed on both sides of each sealing block. The outer periphery of the water inlet is provided with a plurality of first limit slide grooves that are respectively slidably connected to the first limit sliders, and the surface of the rotating ring is provided with a plurality of second limit slide grooves that are respectively slidably connected to the second limit sliders.

[0008] In the above-mentioned industrial water pollution detection sampler, a first gear is rotatably installed on the outer wall of the first sampling box, and the outer end of the driving rod located at the first sampling box is meshed and connected with the first gear. A second gear is rotatably installed on the outer wall of the second sampling box, and the outer end of the driving rod located at the second sampling box is meshed and connected with the second gear.

[0009] In the above-mentioned industrial water pollution detection sampler, a rotating rod is fixedly installed on the lower end of the first gear, and the rotating rod and the second gear are plugged into each other.

[0010] In the above-mentioned industrial water pollution detection sampler, a worm wheel is fixedly mounted on the upper end of the first gear, a worm is fixedly mounted on the outer end of the first motor through its output shaft, and the worm wheel and the worm are connected to each other.

[0011] In the above-mentioned industrial water pollution detection sampler, an insertion cavity is opened in the middle of the second gear, the rotating rod is inserted and installed in the insertion cavity, and a sliding cavity is opened in the middle of the rotating rod, a threaded plate is fixedly installed inside the insertion cavity and is slidably connected to the sliding cavity, and a threaded rod is rotatably installed inside the sliding cavity and is threadedly connected to the threaded plate.

[0012] In the above-mentioned industrial water pollution detection sampler, the lifting mechanism includes a second motor, and the outer end of the second motor is fixedly connected to the rotating shaft at the outer end of the threaded rod through its output shaft.

[0013] In the above-mentioned industrial water pollution detection sampler, the lower ends of the first sampling box and the second sampling box are respectively fixedly installed with a catheter, the upper side of the inner cavity of the catheter is provided with a valve, and the outer ends of the two catheters are respectively fixedly installed with a drainage pipe.

[0015] Compared with existing technologies, the advantages of this industrial water pollution detection sampler are: 1. This device uses a sliding connection between the sealing block, the rotating ring and the inner wall of the sampling box, so that the rotating rotating ring can drive each sealing block to quickly contract or expand on the inside of the water inlet. Compared with the original device that closes the water inlet by rotating the cover, this device can achieve instantaneous interception of industrial wastewater, avoid the mixing of sewage water during non-target periods, and improve the temporal representativeness of sampling.

Through the connection effect between the threaded rod and the threaded plate, it can drive the second sampling box to move up and down on the lower side of the first sampling box, so that the sampling depth spacing of the industrial sewage in the first sampling box and the second sampling box can be adjusted, which can not only improve the representativeness of spatial sampling, but also avoid vertical stratification interference of sewage, thereby improving the sampling quality of industrial sewage.

[0017] 3. The device is provided with a driving mechanism. Through the connection effect between the first gear and the internal driving rod of the first sampling box and between the second gear and the internal driving rod of the second sampling box, the first motor can drive the internal rotating rings of the first sampling box and the second sampling box to rotate at the same time through its output shaft, thereby improving the efficiency of contraction and expansion of each sealing block and significantly improving the consistency of the seal.

[0022] Reference Figures 1-8 A sampler for detecting industrial water pollution comprises a bracket 1, a first sampling box 11 and a second sampling box 12. The first sampling box 11 is connected to the bracket 1 through a wire brush. The second sampling box 12 is plugged into the lower end of the first sampling box 11. Water inlets 2 are provided on the surfaces of the first sampling box 11 and the second sampling box 12. A rotating ring 22 is rotatably installed on the inner side of the water inlet 2. A plurality of sealing blocks 23 that fit each other are slidably installed between the rotating ring 22 and the water inlet 2. A driving mechanism 3 and a lifting mechanism 4 are provided on the outer sides of the first sampling box 11 and the second sampling box 12. The driving mechanism 3 comprises a first motor 30 and two driving rods 37. The two driving rods 37 are respectively arranged in the first sampling box 11 and the second sampling box 12, and adjacent driving rods 37 are meshed with the rotating ring 22.

[0023] A first gear 33 is rotatably installed on the outer wall of the first sampling box 11, and the outer end of the driving rod 37 located at the first sampling box 11 is meshed and connected with the first gear 33. A second gear 35 is rotatably installed on the outer wall of the second sampling box 12, and the outer end of the driving rod 37 located at the second sampling box 12 is meshed and connected with the second gear 35.

[0024] A rotating rod 34 is fixedly mounted on the lower end of the first gear 33 , and the rotating rod 34 and the second gear 35 are plugged into each other.

[0025] An inserting cavity 38 is opened in the middle of the second gear 35, and the rotating rod 34 is inserted and installed in the inserting cavity 38. A sliding cavity 41 is opened in the middle of the rotating rod 34, and a threaded plate 42 that is slidably connected to the sliding cavity 41 is fixedly installed inside the inserting cavity 38. A threaded rod 43 that is threadedly connected to the threaded plate 42 is rotatably installed inside the sliding cavity 41.

[0026] The lifting mechanism 4 includes a second motor 40 , and the outer end of the second motor 40 is fixedly connected to the outer end rotation axis of the threaded rod 43 through its output shaft.

[0027] The specific working principle and method of use of the present invention are explained in detail below: When in use, the position of the first sampling box 11 can be adjusted in the industrial wastewater water area through the bracket 1; When the sampling depth spacing between the first sampling box 11 and the second sampling box 12 needs to be adjusted, the first motor 30 is turned off and the second motor 40 is started. The threaded rod 43 is driven to rotate through its output shaft. Under the restriction of the movement direction of the second gear 35 by the rotating rod 34, the rotating threaded rod 43 can drive the second gear 35 to move up and down through the threaded connection between it and the threaded plate 42. The second gear 35 is rotatably connected to the second sampling box 12, which can drive the second sampling box 12 to move up and down, thereby achieving the effect of adjusting the vertical spacing between the first sampling box 11 and the second sampling box 12. When the two water inlets 2 need to be opened or closed, the second motor 40 is turned off and the first motor 30 is started. The rotating rod 34 is driven to rotate through its output shaft, and the meshing connection between the first gear 33 and the internal driving rod 37 of the first sampling box 11 and the second gear 35 and the internal driving rod 37 of the second sampling box 12 are engaged, and then the meshing connection between the driving rod 37 and the rotating ring 22 can drive the two rotating rings 22 to rotate, thereby driving the inner sealing blocks 23 of the two water inlets 2 to shrink inward or expand outward, thereby achieving the effect of closing or opening the water inlet 2.

[0028] A filter screen 21 is mounted within the water inlet 2. A first limiting slider 25 and a second limiting slider 27 are fixedly mounted on either side of each sealing block 23. The outer periphery of the water inlet 2 is provided with a plurality of first limiting chutes 24 that are slidably connected to the first limiting sliders 25. The surface of the rotating ring 22 is provided with a plurality of second limiting chutes 26 that are slidably connected to the second limiting sliders 27. A worm gear 32 is fixedly mounted on the upper end of the first gear 33. A worm 31 is fixedly mounted on the outer end of the first motor 30 via its output shaft. The worm gear 32 and worm 31 are connected to each other.

[0029] The filter 21 is provided to block large particles of impurities in the industrial wastewater, thereby protecting the internal structures of the first sampling box 11 and the second sampling box 12; The sliding connection between the first limiting slider 25 and the first limiting chute 24 can limit the movement direction of each sealing block 23 inside the water inlet 2, so that the rotating ring 22 can drive each sealing block 23 to retract inward or expand outward through the sliding connection between the second limiting chute 26 and the second limiting slider 27; Through the worm gear 32 and the worm 31, when the first motor 30 is turned off, the rotating rod 34 can be self-locked, limiting the rotation of the rotating rod 34, so that when the second motor 40 drives the threaded rod 43 to rotate through its output shaft, it will not drive the rotating rod 34 to rotate with it, thereby ensuring that the relative height of the first sampling box 11 and the second sampling box 12 is always fixed.

[0030] In addition, a conduit 5 is fixedly mounted at the lower end of each of the first and second sampling boxes 11 and 12. A valve 51 is provided on the upper side of the inner cavity of each conduit 5, and a drainage tube 52 is fixedly mounted on the outer end of each conduit 5. A limit slot 53 is defined at the upper end of the second sampling box 12, and a limit rod 54 is fixedly mounted on the lower end of the outer wall of the upper conduit 5. The limit slot 53 and the limit rod 54 are interlocked.

[0031] A conduit 5 is provided to connect the first sampling box 11 and the second sampling box 12 to an external industrial wastewater recovery device through a drain pipe 52, and the valve 51 is opened to recover the industrial wastewater; Through the plug-in connection between the limiting rod 54 and the limiting slot 53, the movement direction of the second sampling box 12 can be limited on the lower side of the first sampling box 11, so that the rotating threaded rod 43 can drive the second sampling box 12 to move up and down through the threaded connection between it and the threaded plate 42.

[0032] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
