TECHNICAL FIELD
[0001] The present application relates to the technical field of microbial sampling, in particular to a portable environmental microbial sampling device. BACKGROUND
[0002] With the development of society, people's requirements for environmental health are constantly improving, and the microorganisms in the environment are invisible to the naked eye, so it is necessary to sample the microorganisms in the environment. Microorganisms include a large group of biological populations including bacteria, viruses, fungi, and some small protists, microscopic algae, etc. Air, water and soil all contain microorganisms. In the process of environmental detection, it is necessary to sample the microorganisms in water to detect water quality. In addition to physical indicators and chemical indicators, water quality standards also have microbial indicators.
[0003] The existing microbial sampling device can effectively sample different levels and depths in the sampling area when sampling microorganisms in water. However, each sampling can only sample a single water area, and cannot be moved to different water areas (such as the center of the river) for sampling. The sampling range is too small, and cannot meet the needs of multi-point and multi-level sampling. After sampling microorganisms at different depths, if cleaning is not performed, the microorganisms or stains at different levels will mix together, polluting the sampling product and reducing the reliability of the sampling data. Therefore, a portable environmental microbial sampling device is proposed. SUMMARY
[0004] The present application aims to solve the problems in the prior art that each sampling can only sample a single water area, cannot be moved to different water areas (such as the center of the river) for sampling, the sampling range is too small, and cannot meet the needs of multi-point and multi-level sampling. After sampling microorganisms at different depths, if cleaning is not performed, the microorganisms or stains at different levels will mix together, polluting the sampling product and reducing the reliability of the sampling data. Therefore, a portable environmental microbial sampling device is proposed.
[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: A portable environmental microbial sampling device, comprising a main body structure, wherein the bottom of the main body structure is fixedly connected with a moving assembly. The main structure includes a float plate, on both sides of which floating airbags are fixedly installed. A power motor is fixedly connected to the four corners of the bottom of the float plate, and a propeller is fixedly installed at the output end of the power motor. A mounting frame is fixedly connected to the top of the float plate, and a drive motor is fixedly connected to the outer wall of the mounting frame. A rotating shaft is fixedly connected to the output end of the drive motor, and a drum is fixedly connected to the outer surface of the rotating shaft. A sampling water pipe is wound around the outer side of the drum. A sampling head is fixedly connected to the bottom of the sampling water pipe. A collection water pump is installed at the top of the sampling water pipe, and a water delivery pipe is fixedly connected to the water delivery end of the collection water pump. Three water outlet pipes are fixedly connected to the outer wall of the water delivery pipe, and each of the three water outlet pipes has a solenoid valve on its outer wall. A sampling bottle is installed at the outlet end of each of the three water outlet pipes. A pressure pipe is fixedly connected to the end of the water delivery pipe away from the collection water pump, and a pressure pump is fixedly installed on the outer surface of the pressure pipe. A clear water tank is installed at the bottom of the pressure pipe.
[0006] Furthermore, a through groove is provided on the upper surface of the float plate, located directly below the drum. The sampling head extends through the through groove to the bottom of the float plate. By setting the through groove, there is displacement space when the sampling water pipe and the sampling head move up and down.
[0007] Furthermore, a drive gear is fixedly connected to the end of the rotating shaft away from the drive motor, a driven gear meshes with the outer surface of the drive gear, a screw is fixedly connected to the outer surface of the driven gear, and a traction block is threadedly connected to the outer surface of the screw.
[0008] Furthermore, a guide rod is fixedly connected to the upper end of the inner wall of the mounting bracket. The guide rod is arranged parallel to the screw, and one end of the guide rod passes through the traction block and is slidably connected to the traction block. By setting the guide rod, the traction block is guided to avoid misalignment and rotation when the screw drives the traction block to move.
[0009] Furthermore, both the sampling bottle and the water tank are fixedly connected to the upper surface of the float plate.
[0010] Furthermore, the sampling water pipe passes through the traction block at one end near the sampling head and is slidably connected to the traction block. By sliding the sampling water pipe to the traction block, the traction block can be moved to pull and adjust the sampling water pipe.
[0011] Furthermore, the end of the screw away from the driven gear extends through the outer wall of the mounting bracket to the interior and is rotatably connected to the mounting bracket via a bearing, and the end of the rotating shaft away from the drive motor extends through the inner wall of the mounting bracket to the exterior and is rotatably connected to the mounting bracket via a bearing.
[0012] Furthermore, fasteners are fixedly connected to both ends of the bottom of the traction block, and a sponge block is fixedly installed on the top of the fasteners, with the sponge block abutting against the outer surface of the sampling water pipe.
[0013] Furthermore, the mobile assembly includes two mobile housings. Two electric telescopic rods are fixedly connected to the top walls of the two mobile housings, and a waterproof plate is fixedly connected to the bottom of the two electric telescopic rods. Several wheels are provided on the lower surface of the waterproof plate. By setting up the mobile assembly, the sampling device can be carried without being moved, making it convenient for staff. Simultaneously, the two symmetrical mobile assemblies at the bottom of the float plate also act as counterweights in the water, improving the stability of the sampling device on water. A rubber waterproof ring can be provided around the outer edge of the waterproof plate. The waterproof plate's function is to prevent water from entering the mobile housings and contacting the electric telescopic rods, thereby preventing corrosion of the electric telescopic rods.
[0014] Furthermore, a storage battery is fixedly connected to the upper surface of the float plate on the side opposite to the clean water tank. The output end of the storage battery is electrically connected to the power motor, drive motor, water pump, solenoid valve, pressurization pump and electric telescopic rod, respectively. By setting up the storage battery to power the sampling device, the water sampling operation can be completed.
[0015] The present invention has the following beneficial effects: 1. In this invention, the device floats on the water by setting up a float plate and a floating airbag, and is equipped with a power motor and a propeller. The operator can control the speed and direction of the motor wirelessly and drive the propeller to propel the device. This allows the device to move freely in different water areas (such as riverbanks, river centers, upstream and downstream), which increases the sampling range, enables multi-point sampling, avoids the data bias caused by traditional fixed sampling, and more comprehensively reflects the spatial distribution characteristics of microorganisms in the water.
[0016] 2. In this invention, a drive motor, rotating shaft, reel, sampling water pipe, sampling head, collection water pump, water delivery pipe, water outlet pipe, solenoid valve, and sampling bottle are used in combination to accurately collect microbial samples at different depths and store them independently. After each sampling, the pipeline is flushed by a pressure pump and a flushing pipe to remove residual microorganisms and stains, avoid mixed contamination, ensure that the sampling data is not affected by the previous sample, and improve the reliability of the sampling data.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1 like Figure 1 - Figure 6 As shown, the present invention proposes a portable environmental microbial sampling device, which includes a main structure 1 and a movable component 2 fixedly connected to the bottom of the main structure 1. The main structure 1 includes a float plate 101, with floating airbags 102 fixedly installed on both sides of the float plate 101. A power motor 103 is fixedly connected to the four corners of the bottom of the float plate 101. A propeller 104 is fixedly installed at the output end of the power motor 103. A mounting frame 105 is fixedly connected to the top of the float plate 101. A drive motor 106 is fixedly connected to the outer wall of the mounting frame 105. A rotating shaft 107 is fixedly connected to the output end of the drive motor 106. A drum 108 is fixedly connected to the outer surface of the rotating shaft 107. A sampling water pipe 109 is wound around the outer side of the drum 108. The bottom of the sampling water pipe 109... A sampling head 110 is fixedly connected to the sampling water pipe 109. A collection water pump 111 is installed at the top of the sampling water pipe 109. A water supply pipe 112 is fixedly connected to the water supply end of the collection water pump 111. Three water outlet pipes 113 are fixedly connected to the outer wall of the water supply pipe 112. A solenoid valve 114 is installed on the outer wall of each of the three water outlet pipes 113. A sampling bottle 115 is installed at the water outlet end of each of the three water outlet pipes 113. A pressure pipe 116 is fixedly connected to the end of the water supply pipe 112 away from the collection water pump 111. A pressure pump 117 is fixedly installed on the outer surface of the pressure pipe 116. A clean water tank 118 is installed at the bottom of the pressure pipe 116.
[0021] A through groove is provided on the upper surface of the float 101, located directly below the drum 108, and the sampling head 110 extends through the through groove to the bottom of the float 101.
[0022] Sampling bottle 115 and water tank 118 are both fixedly connected to the upper surface of float plate 101.
[0023] The end of the screw 121 away from the driven gear 120 extends through the outer wall of the mounting bracket 105 to the inside and is rotatably connected to the mounting bracket 105 through a bearing. The end of the rotating shaft 107 away from the drive motor 106 extends through the inner wall of the mounting bracket 105 to the outside and is rotatably connected to the mounting bracket 105 through a bearing.
[0024] A battery 126 is fixedly connected to the upper surface of the float 101 on the side opposite to the clean water tank 118. The output end of the battery 126 is electrically connected to the power motor 103, the drive motor 106, the water collection pump 111, the solenoid valve 114, the pressurization pump 117, and the electric telescopic rod 202.
[0025] In this embodiment, the electric telescopic rod 202 is activated to drive the moving wheel 204 to contact the ground and support the sampling device, making it easy for staff to carry and move. The sampling device is then moved to the water's edge and pushed into the water. The sampling device floats on the water surface due to the buoyancy of the float plate 101 and the floating airbag 102. Staff on the shore use a remote control to start the power motor 103 in conjunction with the propeller 104, which propels the propeller 104 to move the sampling device to different water areas to sample microorganisms from different water areas, thus increasing the sampling range and meeting the needs of multi-point and multi-level sampling. When the sampling area is reached, the drive motor 106 on the mounting frame 105 is activated to drive the rotating shaft 107 to rotate. The rotating shaft 107 drives the drum 108 to rotate, and at the same time, it drives the sampling water pipe 109 to move downward and extend into the water. In water at different levels and depths, the sampling head 110 samples microorganisms by activating the sampling pump 111. Solenoid valves 114 on the outlet pipe 113 are opened sequentially according to the depth to which the sampling head 110 descends, collecting microbial samples from different levels and depths into sampling bottles 115 via the supply pipe 112 and outlet pipe 113. After each microbial sample collection, all solenoid valves 114 are closed and the pressure pump 117 is activated. The pressure pump 117 increases the water pressure, enhancing the impact force of the water flow, thereby more effectively flushing the inner walls of the supply pipe 112 and sampling pipe 109 with clean water from the clear water tank 118 through the flushing pipe 116. This prevents microorganisms or dirt from different levels and depths from adhering to the inner walls of the supply pipe 112 and sampling pipe 109, contaminating the samples and affecting the reliability of the sampling data.
[0026] Example 2 like Figure 1 -Figure 6 As shown, based on Embodiment 1, a drive gear 119 is fixedly connected to the end of the rotating shaft 107 away from the drive motor 106. A driven gear 120 meshes with the outer surface of the drive gear 119. A screw 121 is fixedly connected to the outer surface of the driven gear 120. A traction block 122 is threadedly connected to the outer surface of the screw 121.
[0027] A guide rod 123 is fixedly connected to the upper end of the inner wall of the mounting bracket 105. The guide rod 123 is arranged parallel to the screw 121. One end of the guide rod 123 passes through the traction block 122 and is slidably connected to the traction block 122.
[0028] The sampling water pipe 109 passes through the traction block 122 at one end near the sampling head 110 and is slidably connected to the traction block 122.
[0029] Fasteners 124 are fixedly connected to both ends of the bottom of the traction block 122, and a sponge block 125 is fixedly installed on the top of the fasteners 124. The sponge block 125 abuts against the outer surface of the sampling water pipe 109.
[0030] The mobile component 2 includes two mobile boxes 201. Two electric telescopic rods 202 are fixedly connected to the top wall of the two mobile boxes 201. A waterproof plate 203 is fixedly connected to the bottom of the two electric telescopic rods 202. Several moving wheels 204 are provided on the lower surface of the waterproof plate 203.
[0031] In this embodiment, while the drum 108 rotates to wind up the sampling water pipe 109, the rotating shaft 107 drives the drive gear 119 to rotate. The drive gear 119 drives the meshing driven gear 120 to rotate. The driven gear 120 drives the screw 121 to rotate. The screw 121 drives the traction block 122 to move laterally, so that the traction block 122 guides the sampling water pipe 109 to move, thereby allowing the sampling water pipe 109 to be evenly wound around the drum. On the outside of 108, it is not easy for tangling and knotting to occur, thus avoiding the tangling and knotting of the sampling water pipe 109 from affecting the subsequent sampling operation. When the traction block 122 guides and winds the sampling water pipe 109, the fastener 124 below the traction block 122 makes the sponge block 125 stick tightly to the outer surface of the sampling water pipe 109. When the sampling water pipe 109 is raised and lowered, the outer surface of the sampling water pipe 109 is cleaned to prevent mud, sand and dirt from adhering to the outer wall and affecting the winding effect of the sampling water pipe 109.
[0032] Working principle of the invention: The main problem addressed by this embodiment is that each sampling can only be performed on a single body of water, and it is not possible to move to different body of water (such as the center of a river) for sampling. The sampling range is too small, which cannot meet the needs of multi-point and multi-level sampling. Furthermore, if the samples of microorganisms at different depths are not cleaned, the microorganisms or dirt at different levels will mix together, contaminating the samples and reducing the reliability of the sampling data.
[0033] The specific steps are as follows: First, the electric telescopic rod 202 is activated, driving the moving wheel 204 to contact the ground and support the sampling device. The sampling device is then moved to the water's edge and pushed into the water. The sampling device floats on the water surface due to the buoyancy of the float plate 101 and the floating airbag 102. On the shore, staff use a remote control to activate the power motor 103, which works in conjunction with the propeller 104, to move the sampling device to different water areas. Upon reaching the sampling area, the drive motor 106 on the mounting frame 105 is activated, driving the rotating shaft 107 to rotate. The rotating shaft 107 drives the drum 108 to rotate, simultaneously causing the sampling water pipe 109 to move downwards and extend into the water. The sampling head 110 samples microorganisms by starting the sampling pump 111, and the collected microbial samples are collected into the sampling bottle 115 by opening the solenoid valve 114 on one of the outlet pipes 113 through the water supply pipe 112 and the outlet pipe 113. After a single microbial sample is collected, the solenoid valve 114 is closed and the pressurization pump 117 is started to flush the inner wall of the water supply pipe 112 and the sampling water pipe 109 with clean water from the clean water tank 118 through the flushing pipe 116. The sampling water pipe 109 is lowered again, and the sampling head 110 collects microbial samples from different layers and depths again and collects them into other sampling bottles 115.
[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
