Description

Technical Field

[0001] This application relates to the technical field of groundwater sampling. Specifically, it relates to an extraction device for detecting the water quality of underground rivers. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, and evaluating the water quality status. The monitoring scope is very wide, including unpolluted and polluted natural waters (rivers, lakes, seas, and groundwater) and various industrial wastewaters, etc. Water quality detection requires sampling the water at the target detection point. Since underground rivers are deep underground, sampling is relatively difficult, and generally professional extraction devices are used to facilitate the extraction of water samples.

[0003] For example, a water sample extraction device for water quality detection based on environmental protection with the patent number (CN201921500564.6) includes a support base, and is characterized in that: a fixed rod is arranged above the support base, and a connecting rod is fixedly connected to one side of the support base. A sleeve is fixedly connected to one side of the connecting rod. A first turntable is arranged on the front surface of the fixed rod, and a second turntable is arranged below the fixed rod. A fixed rope is arranged between the first turntable and the second turntable. A connecting rope is arranged below the fixed rope. A sampling bucket is arranged below the connecting rope. Two clamping blocks are arranged below the sampling bucket, and a counterweight block is clamped and connected between the two clamping blocks.

[0004] In the above structure, the sampling bucket is placed into the water area at the target point using the fixed rope. Due to the setting of the counterweight block, the sampling bucket will sink in the water, thus extracting the water sample. Using this device, only one water sample can be extracted each time, and the water sample will be mixed with the water in different depth waters during the extraction process, and it is impossible to fixedly extract the water sample at a certain depth.

[0005] Therefore, it is necessary to design an extraction device for detecting the water quality of underground rivers that is convenient for extracting water samples at different depths in the same water area. Summary of the Utility Model

[0006] The content part of this application is used to briefly introduce the concepts, which will be described in detail in the following detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0008] A top plate, and a fixing plate is fixedly connected to the bottom surface of the top plate;

[0009] A plurality of water tanks are evenly mounted on the fixing plate along the height direction of the fixing plate, and a water inlet is formed on the top surface of the water tank;

[0010] A pulling rope, fixedly connected to the top plate;

[0011] Features:

[0012] The extraction device for underground river water quality detection also includes:

[0013] A sealing cover is arranged at the water inlet and is rotatably connected to the water tank;

[0014] An elastic member, a connecting plate is fixedly arranged on the water tank, one end of the elastic member is rotatably connected to the connecting plate, and the other end is fixedly connected to the sealing cover;

[0015] A guide block, wherein a side wall portion of the guide block is concave to form a guide groove extending in a height direction of the fixing plate;

[0016] The abutment block is movably arranged in the guide groove. When the abutment block moves toward the top plate, it can abut against the sealing cover in sequence to drive the sealing cover to flip.

[0017] During the operation, a pulling rope is used to lower the water tank into the underground river. Since a sealing cover and an elastic part are provided, the elastic part can tighten the sealing cover so that the sealing cover is tightly covered on the water inlet. When the target depth is reached, an interference block is provided, and the interference block is moved upward so that the interference block interferes with the sealing cover during movement, driving the sealing cover to flip open, allowing the water sample to enter the water tank at the bottom. When the interference block moves to a certain height, the sealing cover is disengaged from the interference block, and the elastic part tightens the sealing cover to reseal the water inlet. The setting of the sealing cover prevents the water sample from mixing with the water from other waters during the sampling process, and the water sample at a fixed point can be fixedly extracted. Since multiple water tanks are provided, multiple water samples can be taken out at one time.

[0018] Furthermore, an extension plate is fixedly arranged on the sealing cover, and a resistance plate is rotatably arranged on the bottom surface of the extension plate;

[0019] A torsion spring is provided at the rotation connection between the resisting plate and the extending plate, so that the resisting plate always has a rotating force to rotate to be parallel to the extending plate.

[0020] Furthermore, a motor box is fixedly arranged on the top plate, a motor is fixedly installed in the motor box, and an output shaft of the motor is fixedly connected to the rotating shaft;

[0021] A driving rope is wound around the rotating shaft, one end of the driving rope is fixedly connected to the rotating shaft, and the other end of the driving rope is inserted through the top plate and fixedly connected to the abutment block.

[0022] Furthermore, a pressure sensor is fixedly mounted on the bottom surface of the water tank located at the bottom.

[0023] Furthermore, a rotating block is rotatably arranged on the connecting plate, and one end of the elastic member close to the connecting plate is fixedly connected to the rotating block.

[0024] Furthermore, the end of the pulling rope away from the top plate is fixedly connected to the winding shaft, and the pulling rope can be wound around the winding shaft.

[0025] Furthermore, partition plates are fixedly arranged at both ends of the winding shaft, both sides of the partition plates are fixedly connected to the bottom plate, and a plurality of support legs are fixedly installed on the bottom surface of the bottom plate.

[0026] Furthermore, a crank is arranged on one side of the partition plate, and the crank passes through the partition plate and is fixedly connected to the winding shaft.

[0027] The beneficial effects of this application are as follows:

[0028] First, it can fixedly extract water samples at a certain depth, avoiding the mixing of water samples with water in other waters;

[0029] Second, it is convenient to operate and extract multiple water samples in sequence;

[0030] Third, the setting of the pressure sensor can record the depth of the water surface, thereby calculating the depth of each water sample. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0047] Hereinafter, the present disclosure will be described in detail with reference to the drawings and in combination with the embodiments.

[0048] An extraction device for detecting the water quality of underground rivers includes: a top plate 1, a water tank 101, and a pulling rope 102;

[0049] Specifically, the bottom surface of the top plate 1 is fixedly connected to two oppositely arranged fixing plates 103, including a first fixing plate 104 and a second fixing plate 105. Three water tanks 101 are evenly installed on the first fixing plate 104 along the height direction, including a first water tank 106, a second water tank 107, and a third water tank 108. A water inlet 109 is formed on the top surface of each water tank 101.

[0050] One end of the pulling rope 102 is fixedly connected to the top plate 1, and the other end is fixedly connected to the winding shaft 110. When the winding shaft 110 rotates, the pulling rope 102 can be wound around the winding shaft 110; baffle plates 111 are fixedly provided at both ends of the winding shaft 110, and both sides of the baffle plates 111 are fixedly connected to the bottom plate 114, and four supporting legs 112 are fixedly installed on the bottom surface of the bottom plate 114; a crank 113 is provided on one side of the baffle plate 111, and the crank 113 is inserted through the baffle plate 111 and fixedly connected to the winding shaft 110;

[0051] During use, the bottom plate 114 is set above the sampling hole, and the pulling rope 102 can be released by rotating the crank 113, so that the water tank 101 is lowered into the sampling hole of the underground river for sampling.

[0052] The underground river water quality detection extraction device also includes: a sealing cover 2, an elastic member 201, a guide block 202, and a resistance block 203;

[0053] Specifically, the sealing cover 2 is provided on the water inlet 109 of the water tank 101, and the sealing cover 2 is rotatably connected to the water tank 101; a connecting plate 204 is fixedly provided on the side wall of the water tank 101, a rotating block 205 is rotatably connected to the connecting plate 204, an extension plate 206 is fixedly connected to the sealing cover 2, one end of the elastic member 201 is fixedly connected to the rotating block 205, and the other end is fixedly connected to the bottom surface of the extension plate 206, and the elastic member 201 is a spring; a resistance plate 207 is rotatably installed on the bottom surface of the extension plate 206, and a torsion spring is provided at the rotation connection between the resistance plate 207 and the extension plate 206, so that the resistance plate 207 always has a rotation force to rotate to be parallel to the extension plate 206;

[0054] The guide block 202 is fixedly mounted on the second fixed plate 105. The side wall portion of the guide block 202 is concave to form a guide groove 208 extending along the height direction of the second fixed plate 105. The abutment block 203 is movably disposed in the guide groove 208.

[0055] More specifically, a motor box 209 is fixedly mounted on the top plate 1, a motor 210 is fixedly mounted in the motor box 209, an output shaft of the motor 210 is fixedly connected to a rotating shaft 211, a driving rope 212 is wound around the rotating shaft 211, one end of the driving rope 212 is fixedly connected to the rotating shaft 211, and the other end is inserted through the top plate 1 and fixedly connected to the abutment block 203;

[0056] A pressure sensor 213 is also fixedly mounted on the bottom surface of the first water tank 106 to detect whether the water surface of the underground river has been reached; scale lines are marked on the pulling rope 102 to facilitate recording the height of the water surface and the height of the sampling point;

[0057] In the initial state, the resistance block 203 is arranged below the resistance plate 207 on the first water tank 106, the motor 210 is started, the rotating shaft 211 rotates to retract the driving rope 212, and the driving rope 212 drives the resistance block 203 to move upward; during the upward movement of the resistance block 203, it can contact with the resistance plate 207, thereby driving the sealing cover 2 to flip open; when the resistance block 203 moves upward for a certain distance, the resistance plate 207 and the resistance block 203 are out of contact, and the elastic member 201 can pull the sealing cover 2 back, so that the sealing cover 2 is sealed with the water inlet 109 again; after the motor 210 is started once, the resistance block 203 moves to below the resistance plate 207 on the second water tank 107; the water tank 101 is placed in waters of other depths, and the above operation is repeated to take out other water samples;

[0058] Since the contact plate 207 is rotatably arranged on the bottom surface of the extension plate 206, when the contact block 203 is moved upward, the contact plate 207 is blocked by the extension plate 206 and cannot be flipped upward, thereby driving the sealing cover 2 to flip; when the contact block 203 moves downward, the contact block 203 can drive the contact plate 207 to flip, thereby resetting the contact block 203; after the contact plate 207 flips, it can automatically rotate to the initial state due to the torsion spring set.

[0059] The arrangement of the sealing cover 2 and the elastic member 201 enables the water tank 101 to be sealed after sampling, thereby preventing the water sample from mixing with water at other depths, and specifically detecting a water sample at a certain fixed depth; the arrangement of the abutment block 203 enables the sealing covers 2 on multiple water tanks 101 to be opened in sequence by moving the abutment block 203, thereby achieving the taking out of multiple water samples at different depths at one time;

[0060] The setting of the pressure sensor 213 can realize that an alarm is sounded when the water tank 101 reaches the water surface, and the water surface height of the underground river can be recorded. After the pulling rope 102 is further released to reach the target depth, the depth of each water sample can be recorded.

[0061] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
