Description

Technical Field

[0001] The utility model relates to the field of water quality sampling, and more specifically to a water quality sampling device for environmental detection. Background Art

[0002] Existing mechanical water sampling equipment is difficult to collect water samples at the specified sampling depth, and some samples from other water layers will be mixed in. If electronic water sampling equipment is used, although it can collect water samples at the specified sampling depth, its use cost and maintenance cost are higher than mechanical ones, and it is inevitable that the seal will age and cause water ingress failure; in addition, due to changes in underwater pressure, the pressure inside the sampling equipment is inconsistent with the underwater pressure, affecting the water sample collection effect.

[0003] Chinese patent application number: CN202321476809.2, provides a water sampling device for water quality testing. This solution sets a depth adjustment mechanism, utilizes Pascal's law, and adjusts the spring force so that the spring force is equal to the water pressure at the specified depth, thereby achieving the technical effect of the device collecting water samples at the specified sampling depth.

[0004] However, it is not convenient to sample the water body when sampling in shallow water areas, especially when there is silt and debris on the bottom of the water, which makes it difficult to sample the water body. Therefore, a water quality sampling device for environmental testing is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of the utility model is to provide a water quality sampling device for environmental testing. The bottom of the ball contacts the silt at the bottom of the sampling area, and the sampling hole on the dome facilitates the water to flow into the dome and be stored inside the bottom of the ball. After the sampling is completed, the top of the ball drives the sealing plug to descend to seal the sampling hole. The whole is a spherical, spherical sampler. When sampling, it can reduce the interference of silt and avoid directly sucking in a large amount of silt to a certain extent, so that the obtained water sample is relatively more representative of the situation of the water body itself, rather than being overly doped with silt components. It can accurately sample and can more accurately obtain water samples at a specific depth in the water body without being excessively affected by the bottom silt. It improves the pertinence and accuracy of sampling, maintains the integrity of the water sample, helps to reduce the pollution or deterioration of water samples that may be caused by the mixing of silt, and better maintains the original state and properties of the water sample.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A water quality sampling device for environmental testing, comprising: a limiting rod installed at the top of a sampling ball, a driving assembly installed at the top of the limiting rod, and an auxiliary assembly installed at the top of the driving assembly; the sampling ball comprises a ball bottom, a dome fixedly connected to the top of the ball bottom, the ball bottom being in communication with the dome, a sampling hole being formed at the top of the dome, a ball top installed above the ball bottom, the ball top being connected to the limiting rod, the ball top being adapted to the dome, a sealing plug being installed inside the ball top, the sealing plug being adapted to the sampling hole;

[0008] The bottom of the ball contacts the silt at the bottom of the sampling area, and the sampling hole on the dome facilitates the flow of water into the dome and is stored inside the bottom of the ball. After the sampling is completed, the top of the ball drives the sealing plug down to seal the sampling hole to prevent the water from overflowing from the bottom of the ball and inside the dome or the entry of debris, thereby preventing the collected water from being affected. The whole is a sphere, and the spherical sampler can reduce silt interference when sampling. It can avoid directly sucking in a large amount of silt to a certain extent, so that the obtained water sample is relatively more representative of the situation of the water body itself, rather than being overly mixed with silt components. It can take samples accurately and can more accurately obtain water samples at a specific depth in the water body without being excessively affected by the bottom silt. It improves the pertinence and accuracy of sampling, maintains the integrity of the water sample, helps reduce the contamination or deterioration of water samples that may be caused by silt mixing, and better maintains the original state and properties of the water sample.

[0009] Reference Figure 2-Figure 4 As shown, the limiting rod includes a plurality of symmetrically distributed sliding rods, the sliding rods are installed at the top of the ball bottom and located outside the dome, the sliding rods pass through the ball top, the sliding rods are slidably connected to the ball top, and the top ends of the sliding rods are fixedly connected to the connecting rods;

[0010] The ball top can be easily moved by a slide bar to expose the dome and to facilitate sampling through the sampling holes on the dome.

[0011] Reference Figure 3 As shown, the driving assembly includes a disc and a magnetic block. The disc is mounted on the top of the connecting rod. The bottom end of the disc is fixedly connected to an electromagnet. The magnetic block is mounted on the top of the spherical top. The magnetic block and the electromagnet are arranged with the same pole opposite to each other.

[0012] The characteristic of the electromagnet adsorbing the magnetic block when it is energized makes it easy to automatically pull the top of the ball upwards, so that the user can open the top of the ball at a suitable position as needed, and sample water bodies at different depths through the sampling holes in the dome. After the sampling is completed, the electromagnet is powered off, and the electromagnet and the magnetic block are repelled, causing the top of the ball to drop, making it easy to seal the sampling holes in the dome.

[0013] The auxiliary component includes a plurality of support rods arranged at equal intervals, the support rods are installed on the top of the disc, the top of the support rods is fixedly connected to a handle, and the top of the handle is fixedly connected to a colored light.

[0014] The auxiliary component further comprises a floating block, which is installed inside the dome, matched with the bottom of the sphere, and matched with the sampling hole.

[0015] The top of the floating block is fixedly connected with a push rod, and the push rod passes through the sampling hole and the sealing plug.

[0016] The auxiliary component also includes a pressure sensor, which is installed inside the ball top and located at the top of the sealing plug. The pressure sensors are fixedly connected to the ball top and the sealing plug. The pressure sensors are adapted to the push rod and are electrically connected to the colored lights and electromagnets.

[0017] The floating block drives the top rod to move. When water is poured into the bottom of the ball, the floating block floats upward until it hits the sampling hole on the dome to seal the sampling hole. At the same time, the top rod passes through the sealing plug and abuts the pressure sensor. The pressure sensor is subjected to pressure and transmits an electrical signal, which turns on the colored light and turns off the electromagnet. After the electromagnet is turned off, the electromagnet and the magnetic block repel each other, causing the top of the ball to drop, which facilitates the sealing of the sampling hole on the dome. The colored light is turned on to remind the user that the sampling is completed. The user pulls the handle and recovers the sampling ball through the support rod and limit rod.

[0018] In summary, the present invention has the following beneficial effects:

[0019] (1) This solution uses the bottom of the ball to contact the silt at the bottom of the sampling area. The sampling hole on the dome facilitates the flow of water into the dome and is stored inside the bottom of the ball. After the sampling is completed, the top of the ball drives the sealing plug down to seal the sampling hole to prevent the water from overflowing from the bottom of the ball and inside the dome or the entry of debris, thereby preventing the impact on the collected water. The whole is a sphere. The spherical sampler can reduce the interference of silt during sampling and avoid directly sucking in a large amount of silt to a certain extent, so that the obtained water sample is relatively more representative of the situation of the water body itself, rather than being excessively mixed with silt components.

At the same time, the top rod passes through the sealing plug and abuts the pressure sensor. The pressure sensor is subjected to pressure and transmits an electrical signal, so that the colored light is powered on and the electromagnet is powered off. After the electromagnet is powered off, the electromagnet and the magnetic block repel each other, causing the top of the ball to drop, making it easier to seal the sampling hole on the dome. The colored light is powered on to remind the user that the sampling is completed. The user pulls the handle and recovers the sampling ball through the support rod and the limit rod.

[0028] Reference Figures 1-4As shown, a water quality sampling device for environmental testing in a preferred embodiment of the present invention includes a sampling ball 1, a limiting rod 2 is installed on the top of the sampling ball 1, a driving assembly 3 is installed on the top of the limiting rod 2, and an auxiliary assembly 4 is installed on the top of the driving assembly 3; the sampling ball 1 includes a ball bottom 101, a dome 102 is fixedly connected to the top of the ball bottom 101, the ball bottom 101 is communicated with the dome 102, a sampling hole is opened on the top of the dome 102, a ball top 103 is installed above the ball bottom 101, the ball top 103 is connected to the limiting rod 2, the ball top 103 is adapted to the dome 102, a sealing plug 104 is installed inside the ball top 103, and the sealing plug 104 is adapted to the sampling hole;

[0029] The spherical bottom 101 contacts the silt at the bottom of the sampling area, and the sampling hole on the dome 102 facilitates the water to flow into the dome 102 and be stored inside the spherical bottom 101. After the sampling is completed, the spherical top 103 drives the sealing plug 104 to descend to seal the sampling hole to prevent the water inside the spherical bottom 101 and the dome 102 from overflowing or having debris enter, thereby preventing the collected water from being affected. The whole is a spherical sampler. When sampling, it can reduce the interference of silt and avoid directly sucking in a large amount of silt to a certain extent, so that the obtained water sample is relatively more representative of the situation of the water body itself, rather than being overly mixed with silt components. It can accurately sample and can more accurately obtain water samples at a specific depth in the water body without being excessively affected by the bottom silt. It improves the pertinence and accuracy of sampling, maintains the integrity of the water sample, helps to reduce the pollution or deterioration of the water sample that may be caused by the mixing of silt, and better maintains the original state and properties of the water sample.

[0030] Reference Figure 2-Figure 4 As shown, the limiting rod 2 includes a plurality of symmetrically distributed sliding rods 201, which are mounted on the top of the ball bottom 101 and located outside the dome 102. The sliding rods 201 pass through the ball top 103, and are slidably connected to the ball top 103. The top of the sliding rods 201 is fixedly connected to the connecting rod 202.

[0031] The sliding rod 201 facilitates the movement of the spherical top 103 to expose the dome 102 and facilitates sampling through the sampling hole of the dome 102 .

[0032] Reference Figure 3 As shown, the drive assembly 3 includes a disc 301 and a magnet 303. The disc 301 is mounted on the top of the connecting rod 202. The bottom end of the disc 301 is fixedly connected to the electromagnet 302. The magnet 303 is mounted on the top of the spherical top 103. The magnet 303 and the electromagnet 302 are arranged with the same poles facing each other.

[0033] The characteristic of the electromagnet 302 adsorbing the magnetic block 303 when it is energized makes it easy to automatically pull the dome 103 upward, so that the user can open the dome 103 at a suitable position as needed, and sample water bodies at different depths through the sampling holes of the dome 102. After the sampling is completed, the electromagnet 302 is powered off, and the electromagnet 302 and the magnetic block 303 are repelled, causing the dome 103 to drop, so that the sampling holes of the dome 102 can be sealed.

[0034] The auxiliary component 4 includes a plurality of equally spaced support rods 401 . The support rods 401 are mounted on the top of the disc 301 . The top of the support rods 401 is fixedly connected to a handle 402 . The top of the handle 402 is fixedly connected to a colored light 403 .

[0035] The auxiliary component 4 further includes a floating block 404 . The floating block 404 is installed inside the dome 102 . The floating block 404 is adapted to the spherical bottom 101 and the sampling hole.

[0036] A top end of the floating block 404 is fixedly connected to a top rod 405 , which passes through the sampling hole and the sealing plug 104 .

[0037] The auxiliary component 4 also includes a pressure sensor 406, which is installed inside the ball top 103 and located at the top of the sealing plug 104. The pressure sensor 406 is fixedly connected to the ball top 103 and the sealing plug 104. The pressure sensor 406 is adapted to the top rod 405. The pressure sensor 406 is electrically connected to the colored light 403 and the electromagnet 302.

[0038] The floating block 404 drives the top rod 405 to move. When water is poured into the bottom of the ball 101, the floating block 404 floats upward until it hits the sampling hole of the dome 102 to seal the sampling hole. At the same time, the top rod 405 penetrates the sealing plug 104 and abuts the pressure sensor 406. The pressure sensor 406 is subjected to pressure and transmits an electrical signal, so that the colored light 403 is energized and the electromagnet 302 is de-energized. After the electromagnet 302 is de-energized, the electromagnet 302 and the magnetic block 303 repel each other, causing the ball top 103 to descend, thereby sealing the sampling hole of the dome 102. The colored light 403 is energized to remind the user that the sampling is completed. The user pulls the handle 402 and recovers the sampling ball 1 through the support rod 401 and the limit rod 2.

[0039] Specific implementation process: First, the sampling ball 1 is lowered to a suitable water layer through the handle 402. If it needs to contact with silt, the bottom 101 of the ball is brought into contact with the silt at the bottom of the sampling area. Then, the electromagnet 302 is energized to adsorb the magnetic block 303 and pull the top 103 of the ball upward. At this time, the water at the location flows from the sampling hole into the dome 102 and the bottom 101 of the ball. At the same time, the floating block 404 floats upward until it reaches the sampling hole of the dome 102 and blocks the sampling hole. At this time, the top rod 405 penetrates the sealing plug 104 to abut against the pressure. Sensor 406, the pressure sensor 406 is subjected to pressure and transmits an electrical signal, so that the colored light 403 is energized and the electromagnet 302 is de-energized. After the electromagnet 302 is de-energized, the electromagnet 302 and the magnetic block 303 repel each other, causing the ball top 103 to drop. The ball top 103 drives the sealing plug 104 to drop, and the sealing plug 104 seals the sampling hole of the dome 102. The colored light 403 is energized to remind the user that the sampling is completed. The user pulls the handle 402 and recovers the sampling ball 1 through the support rod 401 and the limit rod 2 to complete the sampling.
