Description

Technical Field

[0001] This utility model relates to the field of wastewater sampling technology, specifically a water quality sampling device for factory sewage outlets. Background Technology

[0002] With the rapid development of industry, large amounts of wastewater are often discharged. Since wastewater contains many pollutants, direct discharge into water bodies will greatly damage the ecological environment. Therefore, it is often necessary to have the wastewater sampled by a testing agency and tested to ensure it meets the discharge requirements before it can be discharged.

[0003] An investigation revealed a Chinese utility model patent (authorization announcement number: CN212110735U) disclosing a water quality sampling device. The device comprises a telescopic rod and a sampling assembly. A rotating wheel with a wire rope wound around it is installed near the front end of the telescopic rod, and a pulley is located at the rear end. Several wire rope limiting rings are also provided on the telescopic rod. The wire rope on the rotating wheel passes through the wire rope limiting rings and is wound around the pulley. The sampling assembly includes a sampling cylinder, a partition, an electromagnet, an iron core, a connecting rod, a spring, a microcontroller, and a sealing cap. The partition is located inside the sampling cylinder and divides it into upper and lower areas: a sample storage area and a component installation area. A sample inlet is located at the lower end of the sampling cylinder. This utility model offers advantages such as convenient sampling, automatic sealing after sampling, and effective prevention of sample spillage.

[0004] Although the above-mentioned technical solution can use an electromagnet in conjunction with a partition and an iron core to drive the sampling cylinder to sample sewage, it is relatively slow in operation because it only uses the sampling port and the weight of the cylinder itself to fill the cylinder with water. In addition, in deep water, it is impossible to judge whether the sewage inside the cylinder has been sampled by observation, which makes the sampling process slow. Furthermore, the electromagnet and iron core are relatively delicate components, and replacing them after long-term use is complicated, which is not conducive to the long-term use of the sampling device.

[0005] Therefore, this utility model provides a water quality sampling device for factory sewage outlets to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a water quality sampling device for factory sewage outlets, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A water quality sampling device for a factory sewage outlet includes a barrel, the barrel including a fixed frame fixedly connected above it, a pneumatic tube being provided at the bottom of the fixed frame, and a sampling component being provided inside the barrel.

[0009] The sampling assembly includes a connecting frame fixedly connected to the end of the barrel. A support frame is fixedly connected to the bottom of the connecting frame. A top plate is fixedly connected to the end of the support frame. A pneumatic rod is slidably connected to the inner wall of the pneumatic tube. Multiple rotating seats are fixedly connected to the outer wall of the pneumatic rod. A diagonal support frame for opening the barrel is rotatably connected to the inner wall of the rotating seat. A diagonal support rod is rotatably connected to the inner wall of the top plate. The ends of the diagonal support rod and the diagonal support frame are slidably abutting against the inner wall of the barrel. The diagonal support rod and the middle of the diagonal support frame are rotatably connected by a round shaft.

[0010] A further improvement of the present invention is that the sampling assembly further includes a sampling bucket fixedly connected to the end of the bucket body for sampling, a one-way valve for sample storage fixedly connected to the inner wall of the sampling bucket, and a sieve plate for filtering large solid particles fixedly connected to the end of the sampling bucket.

[0011] A further improvement of this utility model is that: a limiting ring is provided on the outer wall of the sampling barrel, a sliding plate is fixedly connected to the inner wall of the limiting ring to facilitate the opening of the barrel, and a plurality of telescopic blocks are fixedly connected to the inner wall of the limiting ring, and the telescopic blocks are fixedly connected to the outer wall of the barrel.

[0012] A further improvement of this utility model is that: a compression tube for driving the pneumatic rod to slide is fixedly connected inside the pneumatic tube, and a steel wire for taking in and putting out the sampling bucket is wound around the outer wall of the compression tube.

[0013] A further improvement of the present invention is that: a telescopic handheld frame for sampling is provided at the upper end of the barrel, a slot is provided at the end of the telescopic handheld frame, a take-up wheel is rotatably connected to the inner wall of the slot, and multiple wire bundles are fixedly connected to the top of the telescopic handheld frame, the steel wire passes through the inside of the wire bundles and is wound around the inner wall of the take-up wheel.

[0014] A further improvement of this utility model is that: a miniature cylinder for providing power to the pneumatic rod is fixedly connected to the top of the telescopic handheld frame, and a variable diameter sleeve for connecting to the compression pipe is fixedly sleeved at the output end of the miniature cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the elastic barrel body can be folded by the side wall design, and the sampling component changes the air pressure by changing the internal space, so that the sampling barrel at the end can suck the sewage into it through the sieve plate, which replaces the traditional method of natural water filling, greatly improving the sampling speed. The telescopic handrail can make the device adaptable to more sampling environments, and the device can avoid the situation of not knowing the internal sample volume when the traditional natural filling is used, which greatly reduces the difficulty of sampling operation.

[0025] Reference Figures 1-5 This utility model provides two technical solutions: Example

[0026] A water quality sampling device for a factory sewage outlet includes a barrel 1, the barrel 1 includes a fixed frame 101 fixedly connected above it, a pneumatic tube 102 is provided at the bottom of the fixed frame 101, and a sampling component 2 is provided inside the barrel 1.

[0027] The sampling assembly 2 includes a connecting frame 201 fixedly connected to the end of the barrel 1. A support frame 202 is fixedly connected to the bottom of the connecting frame 201. A top plate 203 is fixedly connected to the end of the support frame 202. A pneumatic rod 204 is slidably connected to the inner wall of the pneumatic tube 102. Multiple rotating seats 205 are fixedly connected to the outer wall of the pneumatic rod 204. A diagonal support frame 206 for opening the barrel 1 is rotatably connected to the inner wall of the rotating seat 205. A diagonal support rod 207 is rotatably connected to the inner wall of the top plate 203. The ends of the diagonal support rod 207 and the diagonal support frame 206 are slidably abutting against the inner wall of the barrel 1. The middle of the diagonal support rod 207 and the diagonal support frame 206 are rotatably connected by a round shaft 208.

[0028] The sampling assembly 2 also includes a sampling bucket 209 fixedly connected to the end of the bucket body 1 for sampling. A one-way valve 210 for sample storage is fixedly connected to the inner wall of the sampling bucket 209, and a sieve plate 211 for filtering large solid particles is fixedly connected to the end of the sampling bucket 209.

[0029] Specifically, the elastically folding barrel 1 facilitates submersion into a designated water layer for sampling. The fixing frame 101 provides traction for the barrel 1, preventing instability during descent. The sampling assembly 2 allows for wastewater sampling. The pneumatic rod 204 slides inside the pneumatic tube 102, causing the diagonal support frame 206 on the rotating seat 205 on its side wall to rotate and open. Since the diagonal support frame 206 opens the diagonal support rod 207 via the round shaft 208, the barrel 1 opens from the inside. This opening allows the barrel 1 to... The internal space is altered, and so is the internal pressure. Atmospheric pressure draws wastewater from the sieve plate 211 into the sampling bucket 209. With a fixed opening width, sufficient water can be drawn in at once, avoiding the situation where the water volume in the bucket cannot be obtained when naturally filling. The sieve plate 211 can prevent large particles of solid waste from being drawn into the bucket and causing blockage. The one-way valve 210 on the inner wall of the sampling bucket 209 can prevent the drawn-in wastewater from leaking out of the sampling bucket 209 due to gravity, which can greatly improve the sampling efficiency. Example

[0030] Based on Example 1:

[0031] A limiting ring 3 is provided on the outer wall of the barrel 1, located on the outer wall of the sampling barrel 209. A sliding plate 301 is fixedly connected to the inner wall of the limiting ring 3 to facilitate the opening of the barrel 1. Multiple telescopic blocks 302 are fixedly connected to the inner wall of the limiting ring 3, and the telescopic blocks 302 are fixedly connected to the outer wall of the barrel 1.

[0032] The pneumatic tube 102 is internally fixedly connected to a compression tube 103 for driving the pneumatic rod 204 to slide, and the outer wall of the compression tube 103 is wound with a steel wire 104 for taking in and putting out the sampling bucket 209.

[0033] The upper end of the barrel 1 is provided with a telescopic hand-held frame 105 for sampling. The end of the telescopic hand-held frame 105 is provided with a slot 106. A take-up reel 107 is rotatably connected to the inner wall of the slot 106. Multiple wire bundles 108 are fixedly connected to the top of the telescopic hand-held frame 105. The steel wire 104 passes through the inside of the wire bundle 108 and is wound around the inner wall of the take-up reel 107.

[0034] The top of the telescopic handheld bracket 105 is fixedly connected to a miniature cylinder 109 for providing power to the pneumatic rod 204, and the output end of the miniature cylinder 109 is fixedly sleeved with a variable diameter sleeve 110 for connecting to the compression tube 103.

[0035] Specifically, the micro cylinder 109 drives the variable-diameter sleeve 110 at its output end to transmit high-pressure gas through the connected compression pipe 103 to the pneumatic pipe 102. This causes the pneumatic rod 204 to slide inside the pneumatic pipe 102, thereby causing the sampling component 2 to open the tank 1 and sample the sewage. The telescopic handheld frame 105 allows the device to adapt to more usage scenarios, eliminating the need for traditional throwing sampling methods. This avoids damage to the device during throwing and allows for precise sampling of sewage within a designated area using the telescopic handheld frame 105. For sampling, the take-up reel 107 can be used to wind up the steel wire 104 and its internal compression tube 103 to avoid tangling, making the device easier to carry. The cable tie end 108 can constrain the cable to prevent it from getting tangled during lowering. When the barrel 1 opens outward, the limiting ring 3 can limit the opening of the barrel 1, specifying the opening range and thus controlling the sampling amount. The sliding plate 301 and the telescopic block 302 can further control the telescopic range of the outer wall of the barrel 1, improving the accuracy of the sampling amount.
