Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a rural drinking water safety detection device. Background Art

[0002] Water is the source of life. Human beings cannot live without water in their daily life and production activities. The quality of drinking water is closely related to human health. Some rural reservoirs often use a floating water quality detection alarm model AMT-FB301 to strictly detect drinking water safety. The floating water quality detection alarm has a sensor for water quality detection fixedly installed at the bottom, but the sensor is easily damaged and is not convenient for people to disassemble and replace.

[0003] In this regard, the Chinese patent publication number CN218727213U discloses "a water impurity detection device for new rural drinking water safety, including a floating block, the inner side of the floating block is fixedly connected to a chassis, the inner cavity of the chassis is fixedly connected to a driving motor, the output shaft of the driving motor is fixedly connected to a threaded rod, the surface of the threaded rod is sleeved with a threaded sleeve, the surface of the threaded sleeve is movably connected to a rotating rod through a bearing seat, the other end of the rotating rod is fixedly connected to a mounting plate, the inner wall of the mounting plate is movably connected to a handle through a bearing seat, the surface of the handle is fixedly connected to a main gear, and the surface of the main gear is meshed with a toothed ring";

[0004] The patent drives the "threaded rod" to rotate through the output shaft of the "drive motor", so that the "threaded sleeve" drives the "rotating rod" to move up and down, and the "water quality detector" can be raised and lowered; however, since the "water quality detector" is installed in the water, the bottom end of the "threaded rod" needs to extend into the water, and the "threaded rod" soaked in water for a long time will cause the threads of the "threaded rod" to rust, which makes it difficult for the rusted part to rotate relative to the "threaded sleeve", and the "threaded sleeve" cannot move;

[0005] In addition, the "mounting plate" is connected to the "turning rod", which allows the "mounting plate" to rotate. When the "water quality detector" is installed in the water, the "water quality detector" may be impacted by some water flow. Since the "turning rod" has no locking parts, the "water quality detector" will swing, which will cause the detection position of the "water quality detector" to change, thereby affecting the detection results.

[0024] The following will be combined with 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 of 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.

[0025] Reference Figure 1 - Figure 3 The utility model provides a rural drinking water safety detection device, including a water quality detector 1, an installation mechanism 2 is arranged on the outside of the water quality detector 1, the installation mechanism 2 includes an installation box 21, the installation box 21 is fixedly installed on the floating block 3 and passes through the floating block 3, the inner side of the installation box 21 is provided with a lifting component 22 for driving the water quality detector 1 to rise and fall, the lifting component 22 includes an electric telescopic rod 221, the electric telescopic rod 221 is fixedly installed on the top of the inner side of the installation box 21, the output end of the electric telescopic rod 221 is fixedly installed with a movable seat 222, the movable seat 222 passes through the side wall of the installation box 21, and is slidably connected to the installation box 21, a rotating shaft 224 is rotatably installed on the movable seat 222, one end of the rotating shaft 224 is provided with a positioning component 23 for clamping the water quality detector 1, and the other end of the rotating shaft 224 is provided with a self-locking member 225 for preventing the rotating shaft 224 from swinging.

[0026] By controlling the output end of the electric telescopic rod 221 to extend and retract, the movable seat 222 can be translated in the vertical direction, so that the water quality detector 1 can be translated up and down, and the water quality detector 1 can be installed in the water or taken out of the water; the entire lifting structure will not be affected by water corrosion and has high stability, which solves the problem in the prior art that the screw rod is easily corroded and affects the lifting of the water quality detector 1;

[0027] Reference Figure 1 - Figure 3 A slide groove 223 matching the movable seat 222 is provided on the side wall of the installation box 21 in the vertical direction, and the movable seat 222 can slide along the slide groove 223. The slide groove 223 can ensure that the movable seat 222 slides stably.

[0028] Reference Figure 1 - Figure 4 The self-locking member 225 includes a worm gear 2251, which is fixedly mounted at one end of the rotating shaft 224 and located on the inner side of the mounting box 21. A worm 2252 is rotatably mounted on the movable seat 222, and the worm 2252 is meshed with the worm gear 2251. The worm gear structure has a self-locking property, which can prevent the rotating shaft 224 from rotating autonomously, thereby preventing the water quality detector 1 from swinging when impacted by the water flow, and also preventing the problem of the water quality detector 1 swinging and affecting the detection result.

[0029] Reference Figure 1 - Figure 4 A gear 2253 is fixedly installed at the end of the worm 2252, and a rack 226 is fixedly installed at the top of the inner wall of the installation box 21, and the gear 2253 can mesh with the rack 226.

[0030] Reference Figure 1- Figure 4 , the number of teeth of the rack 226 is half of the number of teeth of the gear 2253. The meshing process of the gear 2253 and the rack 226 can make the gear 2253 rotate half a circle, which makes the rotating shaft 224 rotate 180 degrees, and also makes the water quality detector 1 turn upside down.

[0031] When the water quality detector 1 needs to be replaced, the movable seat 222 is moved upward by the electric telescopic rod 221, so that the water quality detector 1 is taken out of the water. When the movable seat 222 moves to the highest point, the gear 2253 engages with the rack 226, which causes the gear 2253 to rotate, thereby causing the worm 2252 to rotate, and the worm wheel 2251 drives the rotating shaft 224 to rotate synchronously, so that the water quality detector 1 can be turned over 180 degrees as a whole, so that the water quality detector 1 can be turned upward, and the water quality detector 1 can be disassembled. The whole process is simple to operate and is convenient for the installation and disassembly of the water quality detector 1.

[0032] Reference Figure 1 - Figure 5 The positioning assembly 23 includes a mounting plate 231, which is fixedly mounted on the other end of the rotating shaft 224. The mounting plate 231 is provided with a mounting groove 232. A plurality of fixing plates 2321 are fixedly mounted on the edge of the mounting groove 232. The plurality of fixing plates 2321 are evenly distributed around the edge of the mounting groove 232. A penetrating pressure rod 233 is slidably mounted on the plurality of fixing plates 2321. A clamping block 234 is fixedly mounted on one end of the plurality of pressure rods 233. The other end of each of the first wedge blocks 235 is fixedly mounted, and a plurality of pressure rods 233 are sleeved with return springs 236, which are located between the corresponding first wedge blocks 235 and the fixed plate 2321. A rotating cylinder 237 is rotatably mounted on the top of the mounting plate 231, and a plurality of second wedge blocks 238 corresponding to the first wedge blocks 235 are fixedly mounted on the inner wall of the rotating cylinder 237, and the plurality of second wedge blocks 238 can contact the corresponding first wedge blocks 235.

[0033] A positioning pin 239 is slidably installed on the top of the rotating drum 237, one end of which can be inserted into the mounting plate 231, and a tension spring 230 is sleeved on the positioning pin 239, one end of which is fixedly connected to the positioning pin 239, and the other end of the tension spring 230 is fixedly connected to the rotating drum 237, and a positioning hole matching the positioning pin 239 is opened on the mounting plate 231, and the positioning pin 239 slides in cooperation with the positioning hole.

[0034] Working principle of the utility model: when installing the water quality detector 1, the water quality detector 1 is placed in the installation groove 232, and then the rotating drum 237 is rotated to make all the second wedge blocks 238 approach the first wedge blocks 235. When the second wedge blocks 238 contact the corresponding first wedge blocks 235, the first wedge blocks 235 are subjected to the force to make the pressure rod 233 slide. At this time, the return spring 236 is compressed and accumulates potential energy, so that all the clamping blocks 234 contact the water quality detector 1 and clamp it, thus realizing the installation of the water quality detector 1. Finally, the positioning pin 239 is inserted into the corresponding positioning hole, so that the water quality detector 1 is stably installed.

[0035] When disassembling the water quality detector 1, the positioning pin 239 is pulled out from the positioning hole, and then the rotating drum 237 is rotated in the reverse direction to disengage all the second wedge blocks 238 from the corresponding first wedge blocks 235. At this time, all the return springs 236 release the potential energy, so that all the pressure rods 233 slide in the reverse direction, and all the clamping blocks 234 are disengaged from the water quality detector 1. This realizes the disassembly of the water quality detector 1. The whole process is simple to operate and can achieve rapid installation and disassembly of the water quality detector 1.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
