Description

Technical Field

[0001] This utility model belongs to the field of water source detection technology, specifically relating to a drinking water source pollution detection device. Background Technology

[0002] Drinking water sources refer to water sources used to supply people's daily drinking water. These sources need to meet certain water quality standards and hygiene requirements to ensure people's health. Common drinking water sources include natural water bodies such as rivers, lakes, and reservoirs, as well as water extracted from groundwater aquifers, including well water and spring water. This water can be supplied as drinking water after treatment. Drinking water source pollution is closely related to people's health. Common water quality indicators include pH value, dissolved oxygen, ammonia nitrogen, total phosphorus, and total hardness.

[0003] Patent application CN202021831280.8 discloses a drinking water source pollution detection device, including a tank. A support plate is fixed to the left side of the tank, and a pH meter is fixed above the support plate. A detection head is connected to the right side of the pH meter via a wire, and the detection head passes through the left side of the tank and extends into its interior. A retaining ring is fixed to the left side of the inner wall of the tank, and a through hole is formed on the surface of the retaining ring, which is narrower at the top and wider at the bottom. A collar is fixed to the outside of the detection head, and the lower end of the detection head passes through the through hole, with the collar embedded in the through hole. A groove is formed on the right side of the detection head, located inside the collar, and a threaded post is horizontally welded into the groove. This utility model can stir the water in the tank evenly, which is beneficial for the subsequent water quality turbidity meter to detect the turbidity of the water and the pH meter to detect the acidity and alkalinity of the water, and can prevent the detection head from shaking due to the stirring of the water in the tank. In actual testing, sampling from the same water source often needs to be divided into multiple groups and tested repeatedly; however, the detection efficiency of a single testing tank is low, and it cannot simultaneously measure the detection values ​​of multiple groups of samples. Therefore, this application proposes a pollution detection device that can perform multiple group tests simultaneously.

When it is not necessary to fill the test box 10 with water, the partition 8 can be pulled to remove the drain pipes 9 from above the test box 10, making room for the lid 12 to be placed on the test box 10.

[0036] pH meter 14 is fixed on the outside of the front wall of the test box 1 and connected to a test head 15 by a wire; the test head 15 passes through the box cover 12 and its bottom extends into the test box 10.

[0037] In this embodiment, the base 2 includes a first base plate 16 and a second base plate 17. Four limiting posts 18 are provided around the upper surface of the first base plate 16, and compression springs 19 are fitted onto the limiting posts 18. The second base plate 17 is located above the first base plate 16 and has a vibration motor 20 mounted on it. The second base plate 17 also has clearance holes around its perimeter that cooperate with the limiting posts 18. The limiting posts 18 pass through the clearance holes at corresponding positions and are locked in place by nuts. When the vibration motor 20 operates, it can drive the various components located on the second base plate 17 to vibrate. The limiting posts 18 and compression springs 19 around the first base plate 16 provide cushioning and maintain balance.

[0038] Additionally, an inverted L-shaped lifting plate 21 is provided on one side of the cover 12, and a guide groove 22 is provided on the vertical plate of the lifting plate 21; a limiting block 23 is provided on the outer side of the front wall panel of the detection box 1, the limiting block 23 is located in the guide groove 22, and a limiting bolt 24 is provided in the middle of the limiting block 23.

[0039] On the other hand, the limiting frame 3 is equipped with a locking assembly to lock the cover 12 onto the detection box 10, preventing water from spilling out during vibration. The locking assembly includes a cover plate 27, a first clamping plate 28, a second clamping plate 29, a first movable plate 30, and a second movable plate 31; the cover plate 27 is welded to the limiting frame 3, and a sandwich layer is left between the cover plate 27 and the limiting frame 3; a limiting hole 32 is opened in the middle of the cover plate 27, and a rotating shaft 33 is provided in the limiting hole 32 for rotational engagement; a gear 34 is provided on the rotating shaft 33, the inner end of which is rotatably connected to the limiting frame 3, and a lever 35 is provided on the outer end; by moving the lever 35, the rotating shaft 33 and the gear 34 can be rotated; the tops of the first clamping plate 28 and the second clamping plate 29 are both equipped with A limiting baffle 36 is located above the flange plate 213; a movable plate 30 is welded to a clamping plate 28, and a transverse rack 37 is provided at one end of the plate located in the interlayer; a movable plate 31 is welded to a clamping plate 29, and a transverse rack 38 is provided at one end of the plate located in the interlayer; both racks 37 and 38 mesh with gears 34 for transmission, and when gears 34 rotate, they can drive racks 37 and 38 to move in opposite directions, thereby causing clamping plates 28 and 29 to move closer to or further away from each other. When clamping plates 28 and 29 approach each other until they abut against the sides of flange plates 11 and 13, the limiting baffles 36 at the top of clamping plates 28 and 29 move above flange plate 13, preventing flange plate 11 from moving up and down. This prevents the cover 12 from detaching from the test box 10 during device vibration, thus avoiding water spillage from the test box 10. When clamping plates 28 and 29 move away from each other until the limiting baffles 36 move away from flange plate 13, the cover 12 can be moved away from above the test box 10 as the lifting plate 21 rises, facilitating subsequent removal of the test box 10 for cleaning or for the next water sample test.

[0040] It should be noted that the cover plate 27 is also provided with a positioning hole 39, and a limiting screw 40 is provided in the positioning hole 39 for threaded engagement; the end of the lever 35 away from the rotating shaft 33 is provided with a positioning hole 41 through which the limiting screw 40 passes. When it is necessary to lock the cover 12 onto the test box 10, the lever 35 is moved to move the limiting baffle 36 onto the flange plate 13, and then the limiting screw 40 passes through the positioning hole 41 and is screwed into the positioning hole 39, which can prevent the cover 12 from falling off the test box 10 when the device vibrates; after the test is completed, the operator can unscrew the limiting screw 40 from the positioning hole 39, and then move the lever 35 until the limiting baffle 36 is removed from the flange plate 13. At this time, the cover 12 can be removed from the test box 10 by raising the lifting plate 21.

[0041] This utility model's drinking water source pollution detection device, by setting multiple pH meters 14 on the outer side of the front wall of the detection box 1 and inserting the detection head 15 into the box cover 12 of the detection box 10, allows multiple sets of tests to be performed simultaneously when water from the water tank 4 enters the multiple detection boxes 10, which helps to speed up the detection efficiency. By setting a vibration motor 20 to drive the entire device to vibrate before detection, the water in the detection box 10 is prevented from stratifying and settling, which helps to obtain more accurate detection results. It is very practical and has good market application prospects.
