Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality testing technology, specifically a swimming pool water quality testing and sampling mechanism. Background Technology
[0002] The health and safety of swimming pool water quality are mainly reflected in several parameters such as pH and residual chlorine. Low values of these parameters can easily lead to bacterial growth and reproduction, resulting in the spread of skin diseases. High values of these parameters can easily damage human skin and mucous membranes. When people are active in swimming pools, their skin comes into large contact with the water, so the impact of swimming pool water quality on human health cannot be ignored. In order to monitor the water quality of swimming pools and other places in real time, water quality detectors are used to detect the pH and residual chlorine value of the water after disinfection with chlorine-containing chemical reagents. This allows managers to deal with water-related problems in a timely manner, which is crucial for the management of swimming pools.
[0003] Current technology for testing swimming pool water quality typically involves sampling from the pool's edge using sampling tubes. However, since swimming pool water requires disinfection, and disinfectants are usually added at the pool's edge, the diffusion of these disinfectants takes time. Furthermore, some large swimming pools are very large, and the surrounding buildings and trees result in varying lighting conditions at different locations. This lighting directly affects the photodecomposition of chlorine-containing disinfectants. It is also difficult to manually collect water samples from different locations in large swimming pools, and some substances in the water may precipitate. Current technology is not convenient for collecting comprehensive swimming pool water samples. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, the sampling device can be moved to any position in the pool via the traveling mechanism, and water samples at different depths can be obtained via the lifting and lowering water sampling mechanism. This utility model proposes a swimming pool water quality testing sampling mechanism.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a swimming pool water quality testing sampling mechanism, including a sampling box body, a top cover detachably installed on the upper end of the sampling box body, a traveling mechanism provided at the lower part of the sampling box body, a water sample collection mechanism provided inside the sampling box body, and a lifting water collection mechanism provided on the side of the sampling box body.
[0006] The lifting and water-collecting mechanism includes an adjusting motor. The output shaft of the adjusting motor passes through the side of the sampling box body and is fixedly installed on a turntable. A rubber hose is wound inside the turntable. One end of the rubber hose is connected to a sampling port. A lead weight is embedded and fixed outside the sampling port. A water pump is installed inside the sampling box body. The other end of the rubber hose passes through the sampling box body and is connected to the water inlet of the water pump. The water outlet of the water pump is connected to a drain nozzle.
[0007] Preferably, the inner wall of the sampling box body is provided with two sets of symmetrically arranged slots, and the lower end of the upper cover is integrally formed with an elastic block. The upper cover is engaged with the upper end of the sampling box body through the cooperation of the slots and the elastic block. The inner wall of the sampling box body is symmetrically equipped with power supply batteries about respect to the adjustment motor.
[0008] Preferably, a counterweight is embedded in the lower part of the sampling box body, and the traveling mechanism is symmetrically arranged in the lower part of the sampling box body. The traveling mechanism includes a mounting base, in which a brushless motor is installed, and the output shaft of the brushless motor is inserted and fixed with a traveling paddle.
[0009] Preferably, the water sample collection mechanism includes a stepper motor, the counterweight has an inner cavity, the stepper motor is fixedly installed at the bottom of the inner cavity, and the output shaft of the inner cavity is connected to a fixed seat via a keyway, the fixed seat has a fixing groove.
[0010] Preferably, the fixed groove is arranged in a ring array of twelve groups, and the upper part of the fixed groove is provided with an insertion guide groove, and a collection bottle is inserted into the fixed groove.
[0011] Preferably, the upper part of the collection bottle is threaded with a cap, and the upper part of the cap is provided with a water inlet pipe. After the collection bottle is fully inserted into the fixing groove, the upper edge of the water inlet pipe is flush with the lower edge of the liquid discharge nozzle, and the side wall of the water inlet pipe is provided with an inclined pressure relief port.
[0012] Preferably, a limiting ring is glued to the outer side of the sampling box body, and four sets of hooks are glued to the inner wall of the sampling box body. The lower end of the rubber hose is inserted through the limiting ring, and the middle section of the rubber hose is placed on the hook.
[0013] The advantages of this utility model are:
[0014] 1. This utility model allows the entire sampling device to move to any position in the pool via the traveling mechanism at the bottom of the sampling box body. The traveling mechanism is driven by two brushless motors. By controlling the speed and direction of the brushless motors, the traveling direction of the device can be controlled and it can turn around quickly. Furthermore, the counterweight ensures that the traveling mechanism of the sampling box body is always submerged in the water and operates smoothly, thus avoiding water pollution caused by manual sampling.
[0015] 2. This utility model uses the forward and reverse rotation of the adjusting motor in the lifting water intake mechanism to drive the external turntable to rotate. A rubber hose is wound around the turntable. The rotation of the turntable can control the vertical position of the sampling port at the bottom of the rubber hose.

[0025] 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 scope of protection of the present utility model.
[0026] The following is in conjunction with the appendix Figure 1-5 This application provides further details:
[0027] This application discloses a swimming pool water quality testing and sampling device. (Refer to...) Figure 1 and Figure 4 The device includes a sampling box body 1, with a detachable top cover 101 installed on the upper end of the sampling box body 1. Both the sampling box body 1 and the top cover 101 are made of polyethylene plastic. The inner wall of the sampling box body 1 has two sets of symmetrically arranged slots 102, and the lower end of the top cover 101 is integrally formed with an elastic block 103. The top cover 101 is engaged with the upper end of the sampling box body 1 through the cooperation of the slots 102 and the elastic block 103. A sealing ring is also installed at the lower end of the top cover 101, which can reduce the amount of water entering the device from between the sampling box body 1 and the top cover 101 to a certain extent.
[0028] Reference Figure 1 , Figure 4 and Figure 5 The inner wall of the sampling box body 1 is symmetrically equipped with a power supply battery 106 about the adjustment motor 401. The power supply battery 106 is a rechargeable lithium battery. The power supply battery 106 can provide power to the brushless motor 202, stepper motor 301, adjustment motor 401 and water pump 406 in the two travel mechanisms 2.
[0029] Reference Figure 2The sampling box body 1 has a traveling mechanism 2 at its lower part and a counterweight 104 embedded in the lower part of the sampling box body 1. The traveling mechanism 2 is symmetrically arranged at the lower part of the sampling box body 1 and is biased to one side of the sampling box body 1 to balance the weight of the water pump 406. The traveling mechanism 2 includes a mounting base 201, in which a brushless motor 202 is installed. The output shaft of the brushless motor 202 is inserted and fixed with a traveling paddle 203. By controlling the speed and direction of the brushless motor 202, the traveling direction of the device can be controlled and it can turn around quickly.
[0030] Reference Figure 3 and Figure 5 The sampling box body 1 is equipped with a water sample collection mechanism 3 inside, and a lifting water collection mechanism 4 is provided on the side of the sampling box body 1. The water sample collection mechanism 3 includes a stepper motor 301. The counterweight part 104 has an inner cavity 105. The stepper motor 301 is fixedly installed at the bottom of the inner cavity 105, and the output shaft of the inner cavity 105 is connected to a polyethylene fixing seat 302 through a flat key. The fixing seat 302 has twelve sets of fixing slots 303 arranged in a ring array. The upper part of the fixing slot 303 has an insertion guide slot 304. A plastic collection bottle 305 is inserted into the fixing slot 303. The insertion guide slot 304 can guide the collection bottle 305 when it is inserted. Moreover, the diameter of the fixing slot 303 is the same as the outer diameter of the collection bottle 305. The collection bottle 305 will not shake after being inserted. In order to ensure the stability of the device posture when the collection bottle 305 is sampled, the water sample needs to be symmetrically loaded.
[0031] Reference Figure 1 and Figure 3 The upper part of the collection bottle 305 is threadedly connected to the cap 306. The upper part of the cap 306 is provided with a water inlet pipe 307. After the collection bottle 305 is fully inserted into the fixing groove 303, the upper edge of the water inlet pipe 307 is flush with the lower edge of the discharge nozzle 407. The side wall of the water inlet pipe 307 is provided with an inclined pressure relief port 308. After the upper edge of the water inlet pipe 307 is aligned with the lower edge of the discharge nozzle 407, the gap between them is very small. The inclined pressure relief port 308 allows the gas in the collection bottle 305 to be discharged smoothly and prevents the water sample from leaking out of the pressure relief port 308 during the process, thereby making the water intake smoother.
[0032] Reference Figure 1 and Figure 4The lifting and water intake mechanism 4 includes an adjusting motor 401. The adjusting motor 401 and the power supply battery 106 are symmetrically installed to balance the influence of their gravity on the device's posture. The output shaft of the adjusting motor 401 passes through the side of the sampling box body 1 and is fixedly installed with a turntable 402. A rubber hose 403 is wound inside the turntable 402. One end of the rubber hose 403 is connected to a sampling port 404. A lead weight 405 is embedded and fixed to the outside of the sampling port 404. The upper part of the sampling port 404 has anti-slip textures for connecting with the rubber hose 403, and the outside of the sampling port 404 has an embedding groove (see...). Figure 6 The lead sinker 405 is embedded and glued to the outside of the sampling port 404. The outer side of the sampling box body 1 is glued and fixed with a limiting ring 408. By adjusting the low speed rotation of the motor 401 in conjunction with the limiting ring 408, the rubber hose 403 can be prevented from being wound outside the turntable 402 during winding. The lower end of the rubber hose 403 is inserted through the limiting ring 408. The forward and reverse rotation of the adjusting motor 401 in the lifting water collection mechanism 4 drives the rubber hose 403 to be wound and extended. The maximum lower length of the rubber hose 403 is 1.8m, thus achieving the purpose of collecting water samples at different depths.
[0033] Reference Figure 1 The sampling box body 1 is equipped with a water pump 406. The other end of the rubber hose 403 passes through the sampling box body 1 and is connected to the water inlet of the water pump 406. The water outlet of the water pump 406 is connected to a drain nozzle 407. The drain nozzle 407 has an S-shaped structure. Four sets of hooks 409 are attached to the inner wall of the sampling box body 1. The middle section of the rubber hose 403 is placed on the hooks 409. The middle section of the rubber hose 403 has a certain amount of slack, so as to cooperate with the adjustment motor 401 to retract and extend the rubber hose 403.
[0034] Working principle: Before operation, open the top cover 101 and fully insert the collection bottle 305 into the fixing slot 303 of the fixing base 302. Then, control the stepper motor 301 to rotate one revolution to check if the collection bottle 305 is blocked by the drain nozzle 407 because it is not fully inserted. After installation, close the top cover 101 and wash the outside and bottom of the sampling box body 1 with clean water to avoid interference from external contamination. Then, gently place the device into the water from the edge of the pool. Control the direction of travel by the traveling mechanism 2 to reach the sampling position. Then, control the adjusting motor 401 to control the depth of the sampling port 404. After the first sampling is completed, the stepper motor 301 rotates 180° for a second sampling. After sampling is completed, control the traveling mechanism 2 to return to the edge of the pool, open the top cover 101, take out the collection bottle 305 and obtain the water quality sample.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
