DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] Traditionally, when sampling for water quality testing, the sampling box is placed in the water area to be tested for sampling. This means that the sampling box will collect silt into the sampling box when sampling in the water. Since many devices are installed inside the sampling box, the silt will damage the devices inside the sampling box, thereby increasing the cost of water quality sampling.

[0022] In view of this, the utility model provides a water quality detection sampling device that can filter out sediment. The water quality detection sampling device that can filter out sediment solves the problem that in the traditional method of placing the sampling box body into the water area to be detected for sampling, the sediment in the water will enter the sampling box body, causing damage to the internal equipment of the sampling box, through a stirring device, a cleaning device and a collecting device. The device can filter the sediment through the stirring device and the cleaning device to prevent the sediment from entering the equipment inside the sampling box, thereby avoiding the problem of equipment being damaged by sediment.

[0023] Embodiment 1: Figure 1 , 2 , 3 and 4 show that a water quality detection sampling device capable of filtering sediment comprises a shell 1, a water pump 2 is installed on the outer wall of the shell 1, the model of the water pump 2 is: ISG40-200, a water inlet pipe 3 is arranged on the inner wall of the water pump 2, the outer wall of the water inlet pipe 3 is arranged on the shell 1, and a universal wheel 8 is arranged on the bottom of the shell 1. The water quality detection sampling device capable of filtering sediment also comprises: a stirring device 4, installed on the top of the shell 1; a cleaning device 5, arranged inside the shell 1; a collecting device 6, installed below the cleaning device 5; a reminding device 7, arranged above the universal wheel 8; a wall door is arranged on the outer wall of the shell 1, through which samples and sediment can be taken out, and the water inlet pipe 3 can be replaced according to the depth of the water area to be sampled, so as to be suitable for sampling in water areas of different depths; wherein, the stirring device 4 can break up the sediment, the cleaning device 5 can clean up when the stirring device 4 is blocked, the collecting device 6 can collect the water quality for detection, and the reminding device 7 can detect the water level inside the collecting device 6;

[0024] In the specific implementation process, it is worth pointing out that the outer wall of the housing 1 is provided with a wall door, through which the sample and sediment can be taken out, and the water inlet pipe 3 can be replaced according to the depth of the water area to be sampled, so as to be suitable for sampling in water areas of different depths;

[0025] Specifically, when using the water quality detection sampling device that can filter sediment, the staff first pushes the water quality detection sampling device that can filter sediment to the sampling site through the universal wheel 8, and then inserts the water inlet pipe 3 into the sampling water area, and then starts the water pump 2 through the external power supply. The water pump 2 will draw water into the interior of the outer shell 1 through the water inlet pipe 3. At this time, the worker turns on the stirring device 4 to stir the sediment in the water to prevent the sediment from accumulating and causing blockage. The water flow will fall into the collection device 6 through the stirring device 4. When the water level of the collection device 6 rises to the specified position, the reminder device 7 issues a prompt, and the worker turns off the water pump 2 to complete the collection operation. When blockage occurs, the worker can clean the blockage through the cleaning device 5.

[0026] Embodiment 2: By Figure 1 and 2It can be seen that the stirring device 4 includes: a first servo motor 401, the model of the first servo motor 401 is: ECMA-E11320RS, which is rotatably connected to the inner wall of the housing 1 through a bearing; a first vertical rod 402, which is installed at the output end of the first servo motor 401; a stirring rod 403, which is provided with a plurality of them and is all installed on the outer wall of the first vertical rod 402; a filter plate 404, the number of which is not limited and can be satisfied as long as the use requirements are met, which is installed on the inner wall of the housing 1 and is rotatably connected to the outer wall of the first vertical rod 402 through a sealed bearing, and the top of the filter plate 404 is connected to the stirring rod 403. 3; the storage box 405 is plugged into the inner wall of the filter plate 404; the filter plate 404 is processed with a plurality of equidistant openings on the side close to the water pump 2, which can filter the sediment, and the water flow can pass through normally; the filter plate 404 is processed with a large opening on the side away from the water pump 2, and the sediment can fall into the storage box 405 through the large opening, completing the collection of the sediment; wherein the first servo motor 401 can drive the first vertical rod 402 to drive the stirring rod 403 to stir the sediment above the filter plate 404, and the storage box 405 can collect the sediment;

[0027] In the specific implementation process, it is worth pointing out that a plurality of equidistant openings are processed on the side of the filter plate 404 close to the water pump 2, and these openings can filter the silt while the water flow can pass normally. A large opening is processed on the side of the filter plate 404 away from the water pump 2, and the silt can fall into the storage box 405 through the large opening, completing the collection of the silt.

[0028] Specifically, on the basis of the above-mentioned embodiment 1, when water enters the interior of the outer shell 1, the staff turns on the first servo motor 401 through an external power supply. After the first servo motor 401 is powered on, it starts to drive the first vertical rod 402 to rotate. When the first vertical rod 402 rotates, it will drive the stirring rod 403 to rotate. At this time, the mud and sand above the filter plate 404 will be broken up by the stirring rod 403 and enter the interior of the storage box 405, so that the water flow can pass through the filter plate 404 normally. When the sampling is completed, the worker turns off the first servo motor 401. At this time, the stirring rod 403 is no longer subjected to force and stops rotating. The worker can take out the storage box 405 through the wall door set in the outer shell 1 to process the mud and sand uniformly.

[0029] Embodiment 3: By Figure 1 and 2It can be seen that the cleaning device 5 includes: a rotating rod 501, which is rotatably connected to the inner wall of the housing 1 through a sealed bearing; an eccentric wheel 502, which is arranged on the outer wall of the rotating rod 501; a drainage box 503, which is installed at the bottom of the filter plate 404 and is rotatably connected to the outer wall of the rotating rod 501 through a sealed bearing; two baffles 504 are provided, and both are installed on the inner wall of the drainage box 503; a cleaning head 505, which is plugged into the inner walls of the two baffles 504; two first springs 506 are provided, both are sleeved on the outer wall of the cleaning head 505, and are respectively pressed against the outer walls of the two baffles 504; the drainage box 5 The bottom of the filter plate 404 is processed with an opening, and the water flow entering the drainage box 503 can be discharged through the bottom opening. When the cleaning head 505 is inserted into the opening processed by the filter plate 404, the outer wall of the cleaning head 505 will move along the inner wall of the baffle 504 and compress the first spring 506. When the eccentric wheel 502 is separated from the cleaning head 505, the first spring 506 is no longer subjected to force and returns to its original state and drives the cleaning head 505 back to the initial position; wherein, rotating the rotating rod 501 can drive the eccentric wheel 502 to drive the cleaning head 505 to move upward, and the baffle 504 supports the cleaning head 505;

[0030] In the specific implementation process, it is worth pointing out that the bottom of the drainage box 503 is processed with an opening, and the water flow entering the drainage box 503 can be discharged through the bottom opening. When the cleaning head 505 is inserted into the opening processed by the filter plate 404, the outer wall of the cleaning head 505 moves along the inner wall of the baffle 504 and compresses the first spring 506. When the eccentric wheel 502 is separated from the cleaning head 505, the first spring 506 is no longer subjected to force to restore to its original state and drive the cleaning head 505 to return to the initial position;

[0031] Specifically, based on the above-mentioned embodiment 1, when blockage occurs, the staff rotates the rotating rod 501, and the rotating rod 501 is forced to rotate along the inner wall of the outer shell 1 through the bearing, and drives the eccentric wheel 502 to rotate. When the outer wall of the eccentric wheel 502 fits with the bottom of the cleaning head 505, the cleaning head 505 is forced to be lifted up by the eccentric wheel 502. At this time, the cleaning head 505 will be inserted into the opening processed by the filter plate 404, and the sand and gravel blocked in the opening of the filter plate 404 will be pushed out by the cleaning head 505, so that the water flow can pass through the opening processed by the filter plate 404 normally, completing the blockage cleaning operation.

[0032] Embodiment 4: By Figure 1 , 2As can be seen from Figures 4, the collecting device 6 includes: a second servo motor 601, the model of the second servo motor 601 is: ECMA-E11320RS, which is rotatably connected to the outer wall of the housing 1 through a bearing; a second vertical rod 602, installed at the output end of the second servo motor 601; an annular slide rail 604, installed on the inner wall of the housing 1; a horizontal plate 603, installed on the top of the second vertical rod 602, and slidingly engaged with the inner wall of the annular slide rail 604; two containing plates 605 are provided, and both are provided on the inner wall of the horizontal plate 603; two collecting boxes 606 are provided, and both are provided above the containing plates 605; two vertical plates 607 are provided, And they are respectively installed inside the two holding plates 605; two second springs 608 are provided, which are respectively sleeved on the outer walls of the two vertical plates 607 and respectively pressed against the inner walls of the two holding plates 605; two limiting rods 609 are provided, both of which are installed above the horizontal plate 603 and plugged into the inner walls of the two vertical plates 607; wherein the second servo motor 601 can drive the second vertical rod 602 to drive the horizontal plate 603 to rotate along the inner wall of the annular slide rail 604, and make the holding plate 605 drive the collection box 606 to rotate, and the horizontal plate 603 can limit the holding plate 605 through the vertical plate 607, the second spring 608 and the limiting rod 609;

[0033] In the specific implementation process, it is worth pointing out that when the limiting rod 609 is inserted into the inner wall of the vertical plate 607, it can limit the horizontal plate 603 and the containing plate 605, preventing the containing plate 605 from being thrown out due to the centrifugal force when the horizontal plate 603 is rotated under force. When the worker wants to take out the collection box 606, he first lifts the vertical plate 607 upward, and the inner wall of the vertical plate 607 moves along the outer wall of the limiting rod 609 and compresses the second spring 608 until the vertical plate 607 and the limiting rod 609 are separated from each other. At this time, the worker pulls out the containing plate 605 from the inside of the horizontal plate 603, and at the same time, the containing plate 605 will drive the collecting box 606 to be pulled out together, and the worker can take out the collecting box 606.

[0034] Specifically, based on the above-mentioned embodiment 1, when the staff wants to sample the water quality of different waters, firstly, water is pumped into the interior of the outer shell 1 through the water pump 2, and the water flows through the filter plate 404 and the drainage box 503 and then falls into the interior of the collection box 606. When the sampling of a collection box 606 is completed, the worker pushes the water quality detection sampling device that can filter sediment to a new sampling location through the universal wheel 8, and then turns on the second servo motor 601. The second servo motor 601 will drive the second vertical rod 602 to drive the horizontal plate 603 to rotate. When the horizontal plate 603 rotates, it will drive the containing plate 605 and the collection box 606 to rotate. In this way, the two collection boxes 606 can be swapped, so that the empty collection box 606 can continue to sample the water source.

[0035] Embodiment 5: By Figure 1 , 2As can be seen from Figure 3, the reminder device 7 includes: a protective shell 701, two of which are provided and respectively installed on the inner walls of the two collection boxes 606; a third vertical rod 702, two of which are provided and respectively plugged into the inner walls of the two protective shells 701; a pressure sensor 703, the model of which is BSLZ-1, two of which are provided and respectively installed on the inner walls of the two protective shells 701; an alarm 704, the model of which is LTE-1101LK, installed on the top plate of the housing 1; wherein the third vertical rod 702 can move along the inner wall of the protective shell 701 by buoyancy, so that the pressure sensor 703 feeds back a signal to the alarm 704;

[0036] In the specific implementation process, it is worth pointing out that the pressure sensor 703 should be waterproofed, such as by applying waterproof glue, etc. The specific method is not limited, as long as it meets the use requirements. A sealing ring is provided inside the protective shell 701 to prevent the third vertical rod 702 from being affected by buoyancy. When the third vertical rod 702 moves inside the protective shell 701, water flows into the protective shell 701. A float is installed on the outer wall of the third vertical rod 702. When the water level rises to a specified height, the third vertical rod 702 can move upward by inserting the float;

[0037] Specifically, based on the above-mentioned embodiment 1, when the water level inside the collection box 606 rises to the specified position, the third vertical rod 702 will move along the inner wall of the protective shell 701 due to buoyancy until the third vertical rod 702 touches the pressure sensor 703. The pressure sensor 703 will feedback the signal to the alarm 704. After receiving the feedback signal, the alarm 704 will make a sound to remind the workers. The workers will turn off the water pump 2 so that the water source can no longer enter the interior of the outer shell 1, thereby preventing water from overflowing from the collection box 606.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "including an element defined by... does not exclude the existence of other identical elements in the process, method, article or device including the element".
