Abstract
Description
Technical Field
[0001] This application relates to the technical field of water source survey and collection, and particularly relates to a portable forestry water quality information collection and survey device. Background Art
[0002] Forestry water quality information collection refers to the systematic monitoring and data collection of the water quality of water bodies and their surrounding environments in forest ecosystems using professional monitoring equipment and technical methods. This work covers the measurement of various physical, chemical, and biological indicators in water, such as water temperature, pH value, dissolved oxygen content, turbidity, nutrient salt concentration, and pollutant levels, aiming to evaluate the water quality health status and its impact on the forest ecological environment. Through forestry water quality information collection, not only can the quality of water sources and their changing trends be grasped, but also a solid scientific basis is provided for the management, protection, ecological restoration, and rational utilization of forest resources. This process is of great significance for ensuring the health and stability of forest ecosystems.
[0003] When existing forestry water quality information collection and survey devices are working, they can only take samples of water body samples at different depths, and cannot take samples of benthic animal community structures and bottom sludge. Moreover, when existing devices sink to the bottom, the sinking speed is too fast, and the sampler cannot take samples quickly when it reaches the target position, resulting in a small amount of sampled samples. If the opening time of the sampler is increased, the accuracy of the obtained samples will be reduced. Summary of the Invention
[0004] This application proposes a portable forestry water quality information collection and survey device, which has the advantages of sampling the benthic animal community structure and accurate sampling, to solve the problem that existing devices cannot sample the benthic animal community structure and bottom sludge.
[0005] To achieve the above object, this application adopts the following technical solution: A portable forestry water quality information collection and survey device, including a housing, a plurality of partition plates are fixedly connected to the bottom of the housing, a plurality of limiting blocks are fixedly connected to the top and bottom of the partition plates, a sliding plate is arranged between two adjacent partition plates, a sealing ring is arranged in the middle of the sliding plate, a spring is fixedly connected to the top end inside the housing, a ring is fixedly connected to the bottom end of the spring, and two limiting rings are arranged below the ring;
[0006] A plurality of inlet valves, and the plurality of inlet valves are fixedly installed at the bottom of the housing;
[0007] A plurality of exhaust valves, and the plurality of exhaust valves are fixedly installed in the middle of the outer curved surface of the housing;
[0008] Two connecting rings, the connecting rings are fixedly connected to the outer curved surface of the housing, and an elastic membrane is fixedly connected between the two connecting rings;
[0009] A driving mechanism, which is fixedly installed in the middle of the housing;
[0010] A mud taking mechanism, which is fixedly installed on the bottom surface of the housing. The above structure can, when working, open the water inlet valve, so that the water sample passes through the water inlet valve and enters the interior of the housing, and makes the sliding plate slide upward, thereby compressing the space of the gas above. When the gas pressure above is relatively large, the gas will push the ring upward, so that the spring is compressed.
[0011] Preferably, the driving mechanism includes a mounting plate. At the bottom of the mounting plate, a controller, a depth sensor, and a detector are fixedly installed. On the upper surface of the mounting plate, a waterproof housing is fixedly connected. Inside the waterproof housing, a driving motor is fixedly installed. At the top of the output shaft of the driving motor, a transmission shaft is fixedly connected. At the bottom end of the transmission shaft, a fixed plate is rotatably installed. On the curved surface of the transmission shaft, a plurality of fan blades are fixedly connected. The above structure can, when working, when the depth sensor detects that the device is about to reach the collection depth, the controller controls the driving motor to work, thereby driving the transmission shaft and the plurality of fan blades to rotate, so that the sinking speed of the device can be slowed down, and even the device can be in a suspended state at the target collection depth.
[0012] Preferably, the mud taking mechanism includes two fixed ears. At the bottom ends of the two fixed ears, a fixed shaft is fixedly connected. In the middle of the fixed shaft, an inner arm and an outer arm are rotatably installed. Between the top ends of the inner arm and the outer arm, a telescopic rod is fixedly installed. At the bottom ends of the inner arm and the outer arm, a mud digging shell is fixedly connected. The above structure can, when working, by extending the telescopic rod, the distance between the top ends of the inner arm and the outer arm becomes larger, so that the mud digging shells at the bottom ends of the inner arm and the outer arm open, and by shortening the telescopic rod, the two mud digging shells close.
[0013] Preferably, a plurality of grooves are formed in the inner wall of the housing, and the grooves are adapted to the sliding plate.
[0014] Preferably, a plurality of notches are formed at the edge of the sliding plate, and the notches are adapted to the limit blocks.
[0015] Preferably, the water inlet valve is located below the lower limit block, the exhaust valve is located between the two connecting rings, and the limit ring is located above the exhaust valve.
[0016] Preferably, both the mounting plate and the fixed plate are fixedly connected to the housing.
[0017] Preferably, the top ends of the two fixed ears are both fixedly connected to the bottom surface of the housing, and the two mud digging shells are symmetrically arranged. The above structure can, when working, close the two mud digging shells so that an appropriate amount of sludge is contained inside, thereby completing the sampling of the benthic animal community structure, that is, the sludge at the bottom.
[0018] Preferably, the plurality of partition plates are arranged equidistantly in the circumferential direction, and the plurality of water inlet valves are arranged equidistantly in the circumferential direction and the number thereof is equal to the number of partition plates. The above structure can make the water intake equal each time when sampling during operation.
[0019] Preferably, the elastic membrane is made of an elastic material, the sliding plate is made of a plastic with low density, and an appropriate amount of gas is filled above the sliding plate and below the circular ring. The above structure can make the water body enter the interior of the housing through the opened water inlet valve during operation, thereby squeezing the gas above into the space between the elastic membrane and the housing through the exhaust valve, so as to increase the buoyancy of the device.
[0020] The beneficial effects of the present invention are as follows:
[0021] 1. By extending the telescopic rod, the present invention increases the distance between the top ends of the inner arm and the outer arm, so that the dredging shells at the bottom ends of the inner arm and the outer arm open. When the housing is about to reach the bottom of the water, the controller controls the driving motor to drive the transmission shaft and the fan blades to reverse, so that the dredging shells quickly rush towards the sludge at the bottom of the water. Subsequently, the telescopic rod shortens, closing the two dredging shells, so that an appropriate amount of sludge is contained therein, thereby completing the sampling of the benthic animal community structure, that is, the sludge at the bottom. Moreover, through the impact before sampling, the dredging shells can penetrate through sundries such as leaves at the bottom of the water body and the relatively hard soil at the bottom.
[0022] 2. When the depth sensor of the present invention detects that the device is about to reach the collection depth, the controller controls the driving motor to operate, thereby driving the transmission shaft and a plurality of fan blades to rotate, so as to slow down the sinking speed of the device, and even make the device suspended at the target collection depth. When reaching the depth of water body collection, the water inlet valve opens. Due to the water pressure, the water sample passes through the water inlet valve and enters the interior of the housing, thereby completing the sampling at the target depth, solving the problem that the existing equipment sinks too fast, resulting in insufficient sampling or reduced accuracy of the sampling sample.
[0023] 3. By opening the water inlet valve, the present invention enables the water sample to pass through the water inlet valve and enter the interior of the housing, and makes the sliding plate slide upward, thereby compressing the space of the gas above. When the pressure of the gas above is relatively large, the gas will push the circular ring upward, so that the spring is compressed. When the sampling of the bottom sludge is completed, the exhaust valve opens, and the gas above the sliding plate passes through the exhaust valve and enters the space between the elastic membrane and the housing, causing the elastic membrane to expand. Then, by driving the fan blades to rotate at a high speed through the driving motor, the device can be driven to quickly float, thereby realizing rapid sampling. Description of the Drawings

[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.
[0037] Please refer to Figures 1-9, this application discloses a portable forestry water quality information collection and survey device, including a housing 1. A plurality of partition plates 2 are fixedly connected to the bottom of the housing 1. A plurality of limiting blocks 3 are fixedly connected to the top and bottom of the partition plates 2. A sliding plate 4 is arranged between two adjacent partition plates 2. A sealing ring 5 is arranged in the middle of the sliding plate 4. A spring 6 is fixedly connected to the inner top end of the housing 1. The bottom end of the spring 6 is fixedly connected to a circular ring 7. Two limiting rings 8 are arranged below the circular ring 7;
[0038] A plurality of water inlet valves 9 are fixedly installed at the bottom of the housing 1;
[0039] A plurality of exhaust valves 10 are fixedly installed in the middle of the outer curved surface of the housing 1;
[0040] Two connecting rings 11 are fixedly connected to the outer curved surface of the housing 1. An elastic membrane 12 is fixedly connected between the two connecting rings 11;
[0041] A driving mechanism 13 is fixedly installed in the middle of the housing 1;
[0042] A mud sampling mechanism 14 is fixedly installed on the bottom surface of the housing 1;
[0043] Its function is that by opening the water inlet valve 9, the water sample passes through the water inlet valve 9 and enters the interior of the housing 1, and the sliding plate 4 slides upward, thereby compressing the space of the upper gas. When the pressure of the upper gas is relatively large, the gas will push the circular ring 7 upward, so that the spring 6 is compressed. When the sampling of the bottom sludge is completed, the exhaust valve 10 is opened, and the gas above the sliding plate 4 will pass through the exhaust valve 10 and enter the space between the elastic membrane 12 and the housing 1, causing the elastic membrane 12 to expand, so that it can drive the device to float.
[0044] Among them, the driving mechanism 13 includes a mounting plate 131. A controller 132, a depth sensor 133, and a detector 134 are fixedly installed at the bottom of the mounting plate 131. A waterproof housing 135 is fixedly connected to the upper surface of the mounting plate 131. A driving motor 136 is fixedly installed inside the waterproof housing 135. The top of the output shaft of the driving motor 136 is fixedly connected to a transmission shaft 137. The bottom end of the transmission shaft 137 is rotatably installed on a fixing plate 138. A plurality of fan blades 139 are fixedly connected to the curved surface of the transmission shaft 137;
[0045] Its function is that when the depth sensor 133 detects that the device is about to reach the sampling depth, the controller 132 controls the driving motor 136 to work, thereby driving the transmission shaft 137 and multiple fan blades 139 to rotate, so as to slow down the sinking speed of the device, and even make the device suspended at the target sampling depth. When reaching the depth of water body sampling, the water inlet valve 9 is opened. Due to the water pressure, the water sample passes through the water inlet valve 9 and enters the interior of the housing 1, thus completing the sampling at the target depth, and solving the problem that the sinking speed of the existing equipment is too fast, resulting in insufficient sampling or reduced accuracy of the sampling sample.
[0046] Among them, the mud sampling mechanism 14 includes two fixed ears 141. The bottom ends of the two fixed ears 141 are fixedly connected with a fixed shaft 142. The middle part of the fixed shaft 142 is rotatably installed with an inner arm 143 and an outer arm 144. A telescopic rod 145 is fixedly installed between the top ends of the inner arm 143 and the outer arm 144. The bottom ends of the inner arm 143 and the outer arm 144 are both fixedly connected with a dredging shell 146;
[0047] Its function is that by extending the telescopic rod 145, the distance between the top ends of the inner arm 143 and the outer arm 144 becomes larger, so that the dredging shells 146 at the bottom ends of the inner arm 143 and the outer arm 144 open. When the housing 1 is about to reach the bottom of the water, the controller 132 controls the driving motor 136 to drive the transmission shaft 137 and the fan blades 139 to reverse, so that the dredging shells 146 quickly rush towards the sludge at the bottom of the water. Then the telescopic rod 145 shortens, making the two dredging shells 146 close, so that an appropriate amount of sludge is contained inside, thus completing the sampling of the benthic animal community structure, that is, the sludge at the bottom. Moreover, through the impact before sampling, the dredging shells 146 can penetrate through sundries such as leaves at the bottom of the water body and the relatively hard soil at the bottom.
[0048] Among them, a plurality of grooves are formed on the inner wall of the housing 1, which are adapted to the sliding plate 4. A plurality of notches are formed on the edge of the sliding plate 4, which are adapted to the limiting blocks 3. The water inlet valve 9 is located below the lower limiting block 3. The exhaust valve 10 is located between the two connecting rings 11. The limiting ring 8 is located above the exhaust valve 10. The mounting plate 131 and the fixing plate 138 are both fixedly connected with the housing 1. The top ends of the two fixed ears 141 are both fixedly connected with the bottom surface of the housing 1. The two dredging shells 146 are symmetrically arranged. The plurality of partition plates 2 are arranged at equal circumferential intervals. The plurality of water inlet valves 9 are arranged at equal circumferential intervals and the number is equal to the number of the partition plates 2. The elastic membrane 12 is made of an elastic material. The sliding plate 4 is made of a plastic with a small density. An appropriate amount of gas is filled above the sliding plate 4 and below the ring 7;
[0049] Its function is to set several water inlet valves 9 in an open state through the controller 132, then set the opening depth of a certain water inlet valve 9 to the sampling opening depth range, that is, the water sample detection depth or the precise sampling depth of the detector 134, and the remaining water inlet valves 9 are not opened. The exhaust valves 10 are all in an open state. When the device is placed in the water body to be collected, during the sinking process of the device, the water body will enter the interior of the housing 1 through the always-open water inlet valve 9, thereby squeezing the gas above into the space between the elastic membrane 12 and the housing 1, so that the buoyancy of the device increases. Until the device reaches the sampling interval and is in an almost suspended state, at this time the sampling water inlet valve 9 is opened, so as to sample the water body at the target depth, or the detector 134 detects the water sample at the target depth.
[0050] Working principle:
[0051] When taking water samples and detecting the water body, the telescopic rod 145 extends, increasing the distance between the top ends of the inner arm 143 and the outer arm 144, so that the dredging shells 146 at the bottom ends of the inner arm 143 and the outer arm 144 open. The opening depth range of each water inlet valve 9 is set through the controller 132, and then the device is placed in the water body to be collected. The detector 134 keeps working to detect the water body, and the device will sink;
[0052] When the depth sensor 133 detects that the device is about to reach the collection depth, the controller 132 controls the driving motor 136 to work, thereby driving the transmission shaft 137 and multiple fan blades 139 to rotate, so that the sinking speed of the device can be slowed down. When reaching the depth of water body collection, the water inlet valve 9 is opened. Due to the water pressure, the water sample passes through the water inlet valve 9 and enters the interior of the housing 1, and the sliding plate 4 slides upward, thereby compressing the space of the gas above. When the pressure of the gas above is relatively large, the gas will push the ring 7 upward, so that the spring 6 is compressed. The device continues to sink. When leaving the opening depth range of the water inlet valve 9, the water inlet valve 9 will close;
[0053] When all the inlet valves 9 are opened, water samples at different depths are collected inside the housing 1. When the housing 1 is about to reach the bottom, the controller 132 controls the drive motor 136 to drive the transmission shaft 137 and the fan blades 139 to reverse, so that the dredging shell 146 quickly rushes towards the sludge at the bottom of the water. Subsequently, the telescopic rod 145 shortens, so that the two dredging shells 146 close, and an appropriate amount of sludge is contained inside. Subsequently, a plurality of exhaust valves 10 are opened, and the gas above the sliding plate 4 passes through the exhaust valves 10 and enters the space between the elastic membrane 12 and the housing 1, causing the elastic membrane 12 to expand. At the same time, the spring 6 will push the ring 7 downward, allowing more gas to enter the space between the elastic membrane 12 and the housing 1, thereby increasing the buoyancy of the device. At the same time, the controller 132 controls the drive motor 136 to operate, driving the transmission shaft 137 and a plurality of fan blades 139 to rotate at high speed, so that the device can be driven to quickly float upward;
[0054] Take the device out of the water body. Secondly, open the inlet valve 9 in the order of sampling, so as to collect the water sample in the sample container. During the process, the outflow of the water sample can be accelerated by pressing the expanded elastic membrane 12.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
