Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, and in particular relates to a water transparency testing device. Background Technology

[0002] Water transparency testing equipment is a professional instrument used to measure the degree to which suspended matter, colloidal particles, etc. in water obstruct light. It uses a transmitter to emit a light source and a receiver to receive the light source. The attenuation value of the light in the water is collected, and the turbidity parameter is obtained by dividing the attenuation value by the distance.

[0003] Because the attenuation value of clear water is very small, the receiver has difficulty reading out such small attenuation data. The attenuation value can be increased by increasing the distance, but the distance of conventional detection equipment is fixed, which causes the sensitivity of conventional water transparency detection equipment to be unable to be adjusted according to the situation.

[0004] To address this issue, we propose a water transparency testing device. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the sensitivity of conventional water transparency testing equipment cannot be adjusted according to the situation, and to propose a water transparency testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water transparency testing device, comprising:

[0008] A mounting base, with a receiver installed at the lower end of the mounting base;

[0009] A scale, one end of which is fixedly installed on the upper part of the fixing base, and the upper end of the scale is provided with an annular threaded groove along the length direction;

[0010] A slide block is provided with a transmitter at its lower part, and the transmitter is positioned opposite to the receiver. The upper part of the slide block is fitted onto the outer surface of the scale. The slide block is connected to a threaded sleeve via a spring-loaded member. In the natural state of the spring-loaded member, the external thread of the threaded sleeve engages with the threaded groove to achieve relative fixation between the slide block and the scale.

[0011] The above technical solution utilizes a transmitter to emit a light source, which is received by a receiver to obtain an attenuated light signal. The turbidity parameter is obtained by dividing the attenuation value by the distance between the receiver and the transmitter. When the water quality is relatively clear, the spring-loaded component is pulled upward, causing it to disengage the threaded sleeve from the scale, allowing the slide to slide and increasing the distance between the receiver and the transmitter, thus increasing the attenuation sensitivity. When the water quality is relatively turbid, the distance between the receiver and the transmitter is reduced, and the spring-loaded component is lowered to slide the slide back and forth, causing the threaded sleeve to re-engage with the scale. The threaded sleeve is then screwed on to adjust the data to an integer. The threaded sleeve is used to lock the slide, facilitating adjustment as needed.

[0012] In one embodiment, the mounting base includes a first base body with a mounting hole at its upper part. The scale is fixedly installed in the mounting hole, and the receiver is fixedly installed at the lower part of the first base body. The first base body and the mounting hole facilitate the fixing of the receiver and the scale.

[0013] In one embodiment, the scale includes a scale body, which is fixedly connected to the fixing hole. The slide block is slidably mounted on the scale body, and the external thread of the threaded sleeve is adapted to the threaded groove on the upper part of the scale body. The scale body guides the slide block to slide, and the threaded sleeve is threadedly connected to the scale body to lock the slide block and fine-tune its position. The position data of the slide block can be observed through the scale of the scale body, facilitating the adjustment and observation of the slide block's position.

[0014] In one embodiment, the slide includes a second seat, the upper part of which is fixedly connected to a hollow sliding sleeve. The ruler passes sequentially through the sliding sleeve and the second seat and extends outward. The shape of the ruler conforms to the shape of the cavity passing through the sliding sleeve and the second seat. The sliding sleeve is slidably mounted on the ruler, and the second seat is slidably mounted on the ruler. The sliding sleeve increases the sliding guidance range of the slide.

[0015] In one embodiment, the spring-loaded element is a spring sheet, which includes a spring sheet body. One end of the spring sheet body is fixedly connected to a second base body, and the other end of the spring sheet body is fixedly connected to a fixed shaft. The threaded sleeve is fitted onto the outer surface of the fixed shaft, and a push button is fixedly connected to the end of the fixed shaft facing away from the spring sheet body. The elastic force of the spring sheet body acts on the fixed shaft, which in turn acts downwards on the threaded sleeve, keeping the threaded sleeve threadedly engaged with the scale. Pushing the push button upwards causes the fixed shaft to swing upwards against the elastic force of the spring sheet body, disengaging the threaded sleeve from the scale body, thus facilitating the engagement and disengagement of the threaded sleeve from the scale.

[0016] In one embodiment, the spring also includes a stop block fixedly connected to the push button. The stop block prevents the finger from slipping off the push button.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] 1. The transmitter emits a light source, which is received by the receiver to obtain an attenuated light signal. The turbidity parameter is obtained by dividing the attenuation value by the distance between the receiver and the transmitter. When the water quality is relatively clear, the spring-loaded component is pulled upwards, causing the spring-loaded component to disengage from the scale and push the spring-loaded component to move the slide block, increasing the distance between the receiver and the transmitter and increasing the attenuation sensitivity. When the water quality is relatively turbid, the distance between the receiver and the transmitter is reduced, and the spring-loaded component is lowered to slide the slide block back and forth, so that the threaded sleeve and the scale re-engage. The threaded sleeve is screwed on to adjust the data to an integer. The threaded sleeve is used to lock the slide block, which is convenient for adjustment as needed.

[0019] 2. Use the ruler to guide the slide block to slide. The threaded sleeve is connected to the ruler by threads to lock the slide block and fine-tune its position. The position data of the slide block can be observed through the scale of the ruler, which makes it convenient to adjust and observe the position of the slide block.

[0020] 3. Utilize the elastic force of the spring body to act on the fixed shaft, which in turn acts downward on the threaded sleeve, keeping the threaded sleeve and the scale engaged. Push the push button upward, causing the push button to drive the fixed shaft to swing upward against the elastic force of the spring body, allowing the threaded sleeve to disengage from the scale body, making it convenient to operate the engagement and disengagement of the threaded sleeve and the scale.

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0028] like Figure 1 As shown, a water transparency testing device includes:

[0029] Mounting base 2, with receiver 1 installed at the lower end of mounting base 2;

[0030] A scale 3, one end of which is fixedly installed on the upper part of the fixing base 2, and the upper end of the scale 3 is provided with an annular threaded groove (not shown in the figure) along the length direction.

[0031] A slide block 4 has a transmitter 6 mounted on its lower part, which is positioned opposite to the receiver 1. The upper sliding sleeve of the slide block 4 rests on the outer surface of the scale 3. The slide block 4 is connected to a threaded sleeve 7 via a spring-loaded element. In its natural state, the external thread of the threaded sleeve 7 engages with the threaded groove to fix the slide block 4 relative to the scale 3. The receiver 1 and transmitter 6 are electrically connected to an external smart device. It should be noted that the threaded groove is the engagement part, and the threaded sleeve 7 is the locking part. Locking is not limited to the threaded locking method of this application; other methods can also be used to achieve locking.

[0032] like Figure 1 and 2 As shown, the mounting base 2 includes a first base body 21, with a mounting hole 22 on the upper part of the first base body 21. A scale 3 is fixedly installed in the mounting hole 22, and a receiver 1 is fixedly installed on the lower part of the first base body 21. The position of the receiver 1 is fixed by the first base body 21, and the scale 3 is fixed by the mounting hole 22.

[0033] like Figure 1 and 3 As shown, the scale 3 includes a scale body 31, with a lifting hole 32 on the side of the scale body 31. The scale body 31 is fixedly connected to the fixing hole 22. The slide block 4 is slidably mounted on the scale body 31. The external thread of the threaded sleeve 7 is adapted to the threaded groove on the upper part of the scale body. The scale body 31 guides the slide block 4 to slide. The threaded sleeve 7 is threadedly connected to the scale body 31 to lock the position of the slide block 4 and the fine-tuning slide block 4. The position data of the slide block 4 can be observed through the scale of the scale body 31.

[0034] like Figure 1 and 4As shown, the slide block 4 includes a second seat 41, with a hollow sliding sleeve 42 (made of transparent material) fixedly connected to the upper part of the second seat 41. The ruler 31 passes through the sliding sleeve 42 and the second seat 41 in sequence and extends outward. The shape of the ruler 31 is adapted to the shape of the cavity passing through the sliding sleeve 42 and the second seat 41. The sliding sleeve 42 is slidably mounted on the ruler 31, and the second seat 41 is slidably mounted on the ruler 31. The sliding sleeve 42 is used to increase the sliding guide range of the slide block 4.

[0035] like Figure 1 and 5 As shown, the spring-loaded component is a spring piece 5, which includes a spring piece body 51. One end of the spring piece body 51 is fixedly connected to the second base 41, and the other end of the spring piece body 51 is fixedly connected to a fixed shaft 52. A threaded sleeve 7 is fitted onto the fixed shaft 52, extending beyond the sliding sleeve 42 and away from the edge of the second base 41, and contacts the threaded groove at the upper end of the scale 3. A push button 53 is fixedly connected to the end of the fixed shaft 52 facing away from the spring piece body 51. The elastic force of the spring piece body 51 acts on the fixed shaft 52, which in turn acts downward on the threaded sleeve 7, keeping the threaded sleeve 7 threadedly engaged with the scale 3. Pushing the push button 53 upward causes the push button 53 to drive the fixed shaft 52 to swing upward against the elastic force of the spring piece body 51, causing the threaded sleeve 7 to disengage from the scale body 31.

[0036] like Figure 1 and 5 As shown, the spring 5 also includes a stop 54, which is fixedly connected to the push button 53. The stop 54 is used to block the finger and prevent the finger from slipping off the push button 53.

[0037] Working principle: The transmitter 6 emits a light source, which is received by the receiver 1 to obtain an attenuated light signal. The turbidity parameter is obtained by dividing the attenuation value by the distance between the receiver 1 and the transmitter 6. When the water quality is relatively clear, the spring 5 is pulled upward, causing the spring 5 to drive the threaded sleeve 7 to disengage from the scale 3. The spring 5 then pushes the slide block 4 to slide, increasing the distance between the receiver 1 and the transmitter 6 and increasing the attenuation sensitivity. When the water quality is relatively turbid, the distance between the receiver 1 and the transmitter 6 is reduced, and the spring 5 is lowered to slide the slide block 4 back and forth, so that the threaded sleeve 7 re-engages with the scale 3. The threaded sleeve 7 is screwed on to adjust the data to an integer, and the threaded sleeve 7 is used to lock the slide block 4.

[0038] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.
