Description

Technical Field

[0001] This utility model relates to the field of environmental testing technology, specifically to a water quality sampling device for environmental testing. Background Technology

[0002] In the field of environmental monitoring technology, water quality testing is of great significance for assessing water quality and protecting the ecological environment and human health. Water quality encompasses various aspects, including physical characteristics (such as color, turbidity, and odor), chemical characteristics (content of inorganic and organic matter), and biological characteristics (content of bacteria, microorganisms, plankton, and benthic organisms). The establishment of a series of water quality parameters and standards provides a basis for water quality assessment. Currently, water samples are typically collected using water sampling devices, followed by subsequent testing and analysis.

[0003] Existing water quality sampling devices are constantly evolving and innovating. For example, patent CN217587187U discloses a water quality sampling device for environmental testing. This device uses a motor to control the extension and retraction of a measuring scale, thereby controlling the up-and-down movement of the water collection bucket. The submersion depth of the water collection bucket is determined based on the scale lines. An electric push rod controls the opening and closing of the bottom cover to complete the water sample collection at the target depth. At the same time, a one-way valve can prevent the upper layer of water sample from mixing in during the up-and-down movement of the water collection bucket, thus ensuring the purity and accuracy of the water sample to a certain extent.

[0004] However, in-depth research has revealed that there is still room for improvement in this type of sampling device. Firstly, in terms of the connection structure, the fixing mechanism between the measuring ruler and the water collection bucket uses a sliding groove and a snap-locking method to fix the fixing block and the mounting block. During the submersion and ascent of the water collection bucket, it is easily affected by factors such as water flow impact and its own shaking, which can cause the snap-locking to loosen. This can lead to the fixing block sliding out of the sliding groove of the mounting block, causing the water collection bucket to fall off. This can not only result in the loss of the collected water sample, but may also cause equipment damage or pose a safety hazard to the surrounding environment.

[0005] Secondly, although the device is equipped with a one-way valve at the outlet to prevent water from entering during the descent of the collection bucket, impurities such as weeds in the water may still enter the collection bucket during sampling, which can easily cause blockages during the pouring of water samples, greatly reducing the ease of use of the sampling device. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an environmental testing water quality sampling device that has the advantages of stable connection and smooth water flow, and solves the problems in existing devices where the connection between the measuring ruler and the water collection tank is easy to loosen, causing the water collection tank to fall off easily and impurities in the water to clog the one-way valve in the water outlet.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmental testing water quality sampling device, comprising a water collection bucket, a bottom cover, an electric push rod, a winding device, and a measuring scale. The winding device is disposed on the top of the water collection bucket, and the measuring scale is disposed inside the winding device. The electric push rod is fixedly installed on the top inside the water collection bucket. The bottom of the water collection bucket is open. The bottom cover is fixedly installed on the output end of the electric push rod. A water outlet is fixedly installed on the top right side of the surface of the water collection bucket, and the water outlet is connected to the water collection bucket. The top of the water outlet is connected by a hinge. The water collection tank is connected to a cover plate. Connecting mechanisms are fixedly connected to the left and right sides of the top of the water collection tank. Each connecting mechanism includes a support block, which is fixedly connected to the left and right sides of the top of the water collection tank. A bidirectional screw is movably connected inside the support block via a bearing. Clamping plates are threaded onto the left and right sides of the surface of the bidirectional screw. The end of the measuring scale furthest from the winding device is located inside the clamping plate. An anti-accidental opening component is fixedly connected to the front of the water outlet. A limit component is provided at the bottom inside the clamping plate. A clamping component is fixedly connected to the inner side of the clamping plate.

[0008] As a preferred embodiment of this utility model, the anti-accidental opening component includes an L-block, which is fixedly connected to the front of the water outlet bucket. A fixing rod is slidably connected to the top of the L-block, and the rear side of the surface of the fixing rod contacts the cover plate.

[0009] As a preferred embodiment of the present invention, the limiting component includes a limiting hole, which is opened at the bottom inside the clamping plate. A limiting rod is slidably connected inside the limiting hole, and both ends of the limiting rod are fixedly connected to the inner side of the support block.

[0010] As a preferred embodiment of the present invention, the clamping assembly includes a locking plate, which is fixedly connected to the inner side of the clamping plate. The inner side of the locking plate is provided with toothed grooves, and the two toothed grooves can mesh with each other.

[0011] As a preferred embodiment of this utility model, a clamping spring is sleeved on the surface of the fixing rod, and a force-applying block is fixedly connected to the rear side of the surface of the fixing rod, with the spring located between the L-plate and the force-applying block.

[0012] As a preferred embodiment of this invention, a limiting block is fixedly connected to the front end of the fixing rod, and the diameter of the limiting block is larger than the diameter of the fixing rod.

[0013] As a preferred embodiment of this invention, a plum blossom handle is fixedly installed on the left side of the bidirectional screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the design of the connecting mechanism, limiting component, and clamping component, utilizes a bidirectional screw to drive the clamping plate to move, which, in conjunction with the toothed locking plate in the clamping component, engages with each other to firmly clamp the measuring ruler inside the clamping plate. This greatly enhances the stability of the connection between the measuring ruler and the water collection bucket, reduces safety hazards, and the water outlet effectively prevents blockage when pouring water samples. It solves the problems in existing devices where the connection between the measuring ruler and the water collection bucket is prone to loosening, causing the water collection bucket to fall off easily, and impurities in the water to easily clog the one-way valve in the water outlet, achieving a stable connection and smooth water flow.

[0016] 2. This utility model incorporates an anti-accidental opening component. During sampling, the cover plate is connected to the top of the water outlet via a hinge and is in a normally closed state. When it is necessary to prevent the cover plate from opening accidentally, the fixing rod is in its initial position inside the L-block, with its rear surface abutting against the cover plate to restrict the cover plate from rotating around the hinge and opening.

[0017] 3. By setting a limiting component, when the bidirectional screw rotates, it drives the clamping plates on both sides to move along the bidirectional screw to clamp or release the measuring scale. During this process, the limiting hole at the bottom of the clamping plate is fitted onto the limiting rod. The limiting rod provides guidance for the movement of the clamping plate and restricts the clamping plate to slide only along the axial direction of the limiting rod, avoiding the clamping plate from shifting or shaking during the movement, and ensuring that the clamping plate can stably clamp the measuring scale.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, this utility model provides an environmental testing water quality sampling device, including a water collection bucket 1, a bottom cover 2, an electric push rod 3, a winding device 4, and a measuring ruler 5. The winding device 4 is located on the top of the water collection bucket 1, and the measuring ruler 5 is located inside the winding device 4. The electric push rod 3 is fixedly installed on the top inside the water collection bucket 1. The bottom of the water collection bucket 1 is open. The bottom cover 2 is fixedly installed on the output end of the electric push rod 3. A water outlet 6 is fixedly installed on the top right side of the surface of the water collection bucket 1. The water outlet 6 is connected to the water collection bucket 1, and a cover plate 7 is movably connected to the top of the water outlet 6 via a hinge. A connecting mechanism 8 is fixedly connected to the left and right sides of the top of the water bucket 1. The connecting mechanism 8 includes a support block 81, which is fixedly connected to the left and right sides of the top of the water collection bucket 1. A bidirectional screw 82 is movably connected to the inside of the support block 81 through a bearing. A clamping plate 83 is threadedly connected to the left and right sides of the surface of the bidirectional screw 82. The end of the measuring ruler 5 away from the winding device 4 is located inside the clamping plate 83. An anti-accidental opening assembly 9 is fixedly connected to the front of the water outlet 6. A limit assembly 84 is opened at the bottom inside the clamping plate 83. A clamping assembly 85 is fixedly connected to the inner side of the clamping plate 83.

[0025] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The anti-accidental opening assembly includes an L-block 91, which is fixedly connected to the front of the water outlet 6. A fixing rod 92 is slidably connected to the top inside the L-block 91, and the rear side of the surface of the fixing rod 92 is in contact with the cover plate 7.

[0026] As a technical optimization of this utility model, by setting up an anti-accidental opening assembly of 9 pieces, during the sampling process, the cover plate 7 is connected to the top of the water outlet 6 via a hinge and is in a normal closed state. When it is necessary to prevent the cover plate 7 from opening accidentally, the fixing rod 92 is in the initial position inside the L block 91, and its rear side abuts against the cover plate 7, restricting the cover plate 7 from rotating and opening around the hinge.

[0027] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The limiting component 84 includes a limiting hole 841, which is opened at the bottom inside the clamping plate 83. A limiting rod 842 is slidably connected inside the limiting hole 841, and the two ends of the limiting rod 842 are fixedly connected to the inner side of the support block 81.

[0028] As a technical optimization of this utility model, by setting a limiting component 84, when the bidirectional screw 82 rotates, it drives the clamping plates 83 on both sides to move along the bidirectional screw 82 to clamp or release the measuring ruler 5. During this process, the limiting hole 841 at the bottom of the clamping plate 83 is fitted onto the limiting rod 842. The limiting rod 842 provides guidance for the movement of the clamping plate 83, restricting the clamping plate 83 to slide only along the axial direction of the limiting rod 842, avoiding the clamping plate 83 from shifting or shaking during the movement, and ensuring that the clamping plate 83 can stably clamp the measuring ruler 5.

[0029] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The clamping assembly 85 includes a locking plate 851, which is fixedly connected to the inner side of the clamping plate 83. The inner side of the locking plate 851 is provided with a toothed groove 852, and the two toothed grooves 852 can mesh with each other.

[0030] As a technical optimization of this utility model, by setting up a clamping assembly 85, when the bidirectional screw 82 is rotated to move the clamping plates 83 on both sides toward the middle to clamp the measuring ruler 5, the locking plates 851 on the inner side of the clamping plates 83 move closer together, and the tooth grooves 852 on the inner side of the two locking plates 851 mesh with each other. Through the meshing of the tooth grooves 852, the friction force on the measuring ruler 5 is increased, forming a more solid clamping effect. Even if the measuring ruler 5 is pulled by external force, the meshing of the tooth grooves 852 can effectively prevent the measuring ruler 5 from slipping off between the clamping plates 83.

[0031] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A retaining spring 10 is sleeved on the surface of the fixing rod 92, and a force-applying block 11 is fixedly connected to the rear side of the surface of the fixing rod 92. The spring is located between the L plate and the force-applying block 11.

[0032] As a technical optimization of this utility model, by setting a clamping spring 10 and a force-applying block 11, the spring force is used to realize the automatic clamping of the fixing rod 92 against the cover plate 7, without the need for continuous manual force application, making the operation more convenient and efficient. The clamping force of the fixing rod 92 against the cover plate 7 is enhanced, which can better resist the risk of the cover plate 7 being accidentally opened due to external vibration, collision and other factors, further ensuring the sealing of the water outlet 6, preventing water sample spillage and impurities from entering, and improving the practicality and reliability of the sampling device.

[0033] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The front end of the fixing rod 92 is fixedly connected to a limiting block 12, and the diameter of the limiting block 12 is larger than the diameter of the fixing rod 92.

[0034] As a technical optimization of this utility model, by setting a limiting block 12, the limiting block 12 is fixed to the front end of the fixed rod 92. Its large diameter forms a blocking structure. During the sliding process of the fixed rod 92, when the fixed rod 92 is pulled to a certain position, the limiting block 12 contacts the front end of the L block 91, preventing the fixed rod 92 from continuing to slide forward and detaching from the L block 91, ensuring that the fixed rod 92 always slides inside the L block 91 and will not be lost or damaged due to excessive pulling.

[0035] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A plum blossom handle 13 is fixedly installed on the left side of the bidirectional screw 82.

[0036] As a technical optimization of this utility model, by setting the plum blossom handle 13, it is easy for the operator to grip and apply force. Even when the hands are wet or gloves are worn, the bidirectional screw 82 can be easily rotated to quickly adjust the clamping degree of the measuring ruler 5.

[0037] The working principle and usage process of this utility model are as follows: First, connect the water collection tank 1 to the measuring ruler 5. The operator rotates the plum blossom handle 13 on the left side of the bidirectional screw 82, causing the clamping plates 83 on both sides to move towards each other along the limiting rod 842. The locking plates 851 with toothed grooves 852 engage with each other, securely clamping the measuring ruler 5, thus completing the connection between the measuring ruler 5 and the water collection tank 1. Next, check and ensure that the cover 7 of the water outlet 6 is closed and that the fixing rod 92 is against the cover 7. Then, start the winding device 4, and control the water collection tank 1 to slowly descend to the target depth using the measuring ruler 5. Once the target depth is reached... Start the electric push rod 3. The output end of the electric push rod 3 extends, causing the bottom cover 2 to move downwards and open the bottom opening of the water collection tank 1. Water enters the water collection tank 1 to complete the water sample collection. After the collection is completed, the electric push rod 3 retracts, causing the bottom cover 2 to move upwards and close the bottom opening of the water collection tank 1. After the collection is completed, start the winding device 4 again. Use the measuring ruler 5 to lift the water collection tank 1 above the water surface. When it is necessary to use the water in the water collection tank 1, pull the fixing rod 92 backwards to overcome the elastic force of the retaining spring 10, so that the rear side of the fixing rod 92 is disengaged from the cover plate 7. Open the cover plate 7 and pour the water sample in the water collection tank 1 out from the water outlet 6 for use.

[0038] In summary, this environmental testing water quality sampling device, through the design of the connecting mechanism 8, the limiting component 84, and the clamping component 85, utilizes a bidirectional screw 82 to drive the clamping plate 83 to move. This, combined with the interlocking of the locking plate 851 with toothed grooves 852 in the clamping component 85, securely clamps the measuring ruler 5 to the inside of the clamping plate 83. This greatly enhances the stability of the connection between the measuring ruler 5 and the water collection bucket 1, reducing safety hazards. The water outlet 6 effectively prevents blockage when pouring water samples, solving the problems of easy loosening of the connection between the measuring ruler and the water collection bucket in existing devices, leading to the easy detachment of the water collection bucket and the easy clogging of the one-way valve in the water outlet by impurities in the water.
