Description

Technical Field

[0001] This utility model belongs to the field of water environment testing technology, and in particular relates to an ammonia nitrogen detector for water environment testing. Background Technology

[0002] Ammonia nitrogen detectors for water environment monitoring are specialized instruments used to determine the ammonia nitrogen content in water bodies, playing an important role in environmental protection, water treatment, and other fields.

[0003] Existing ammonia nitrogen detectors for water environment monitoring are typically mounted on floating boats and submerged in the water. However, due to the presence of large amounts of solid debris such as branches and stones in the water, the floating boat is prone to colliding with these objects while moving the detector, causing damage. This not only affects water environment monitoring but also results in economic losses and increased operating costs. Therefore, we propose a new ammonia nitrogen detector for water environment monitoring. Utility Model Content

[0004] The purpose of this utility model is to provide an ammonia nitrogen detector for water environment testing. By setting up a protective component, specifically by pulling the protective cover downwards until it contacts the limiting ring, and inserting the threaded shaft into the protective cover, then installing a nut on the threaded shaft to fix the protective cover, and finally connecting the cover plate to the bottom of the protective cover via threads, the protective cover and cover plate serve to protect the ammonia nitrogen detector, preventing direct collisions with branches or stones. This effectively protects the ammonia nitrogen detector from damage, reduces economic losses, and solves the problem that existing ammonia nitrogen detectors used for water environment testing are easily damaged by collisions with branches or stones during water testing, which not only affects water environment monitoring but also causes economic losses.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an ammonia nitrogen detector for water environment testing, comprising a floating boat, a controller fixedly connected to the top of the floating boat, a baffle set on the back of the controller, the bottom of the baffle fixedly connected to the top of the floating boat, a protective assembly set below the floating boat, the protective assembly including a protective cover, a cover plate threadedly connected to the bottom of the protective cover, several openings opened inside the protective cover and inside the cover plate, a connecting block inserted into the center of the protective cover, an ammonia nitrogen detector fixedly connected to the bottom of the connecting block, a limit ring fixedly connected to the outer surface of the connecting block, the top of the limit ring contacting the top of the inner side of the protective cover, several threaded shafts fixedly connected to the top of the limit ring, and nuts threadedly connected to the outer surface of the several threaded shafts.

[0007] A drive propeller is fixedly connected to the bottom of the floating boat. A circular hole is opened in the center of the floating boat. A fixed cylinder is fixedly connected to the inner wall of the circular hole in the center of the floating boat. A fixed frame is set in front of the fixed cylinder. The top of the fixed frame is fixedly connected to the bottom of the floating boat. A square slot is opened at the bottom of the fixed frame.

[0008] A square rod is fixedly connected to the top of the protective cover, and a diamond-shaped spring is fixedly connected to the top of the square rod. The square rod is compatible with a square slot.

[0009] The fixed cylinder has an internal threaded rod inside, and the internal threaded rod is connected to a threaded rod inside. The bottom of the internal threaded rod is fixedly connected to the top of the connecting block.

[0010] The casing is equipped with a fixed base, the bottom of which is fixedly connected to the top of the floating boat. A motor is fixedly connected to the top of the fixed base, and a gear one is fixedly connected to the bottom output end of the motor. Gear one is meshed with gear two on the front. A stabilizing frame is provided in front of the fixed base, and the bottom of the stabilizing frame is fixedly connected to the top of the floating boat.

[0011] The top of the threaded rod passes through the stabilizer and extends to the bottom of the second gear for a fixed connection. The top of the threaded rod is rotatably connected to the center of the stabilizer. Three protrusions are fixedly connected to the outer surface of the internal threaded rod. Limiting strips are slidably connected to both sides of the three protrusions. The side of the limiting strip away from the internal threaded rod is fixedly connected to the inner wall of the fixed cylinder.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up a protective component, specifically involves pulling the protective cover downwards until it contacts the limiting ring, and inserting the threaded shaft into the protective cover. Then, a nut is installed on the threaded shaft to fix the protective cover. Subsequently, a cover plate is threadedly connected to the bottom of the protective cover. The protective cover and cover plate then serve to protect the ammonia nitrogen detector, preventing branches or stones from directly colliding with the ammonia nitrogen detector, effectively protecting the ammonia nitrogen detector from damage and reducing economic losses.

[0014] 2. This utility model uses a fixed cylinder. Specifically, the starting motor drives gear one to rotate, which in turn drives the threaded rod to rotate through gear two. The internal threaded rod then moves up or down. By controlling the forward or reverse rotation of the threaded rod, the lifting and lowering of the internal threaded rod can be adjusted, thereby adjusting the depth of the ammonia nitrogen detector. This allows for the detection of water environments at different depths, meeting various detection needs.

[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] Please see Figure 1-6As shown, this utility model is an ammonia nitrogen detector for water environment testing, including a floating boat 1. A controller 11 is fixedly connected to the top of the floating boat 1. A cover 12 is provided on the back of the controller 11. The bottom of the cover 12 is fixedly connected to the top of the floating boat 1. A protective component 13 is provided below the floating boat 1. The protective component 13 includes a protective cover 131. A cover plate 132 is threadedly connected to the bottom of the protective cover 131. Several openings are provided inside both the protective cover 131 and the cover plate 132. A connecting block 133 is inserted into the center of the protective cover 131. An ammonia nitrogen detector 331 is fixedly connected to the bottom of the connecting block 133. A limit ring 134 is fixedly connected to the outer surface of the connecting block 133. The top of the limit ring 134 is connected to the protective cover 131. The inner top contact and the top of the limiting ring 134 are fixedly connected to several threaded shafts 341, and the outer surfaces of the several threaded shafts 341 are all threaded with nuts 342; pull the protective cover 131 down until it contacts the limiting ring 134 and the threaded shafts 341 are inserted into the protective cover 131, and then install the nuts 342 on the threaded shafts 341 to fix the protective cover 131. Then, the cover plate 132 is threadedly connected to the bottom of the protective cover 131. The protective cover 131 and the cover plate 132 are used to protect the ammonia nitrogen detector 331, preventing branches or stones from directly colliding with the ammonia nitrogen detector 331, effectively protecting the ammonia nitrogen detector 331 from damage and reducing economic losses.

[0027] A drive propeller 2 is fixedly connected to the bottom of the floating boat 1. A circular hole is opened at the center of the floating boat 1. A fixed cylinder 15 is fixedly connected to the inner wall of the circular hole at the center of the floating boat 1. A fixed frame 14 is set in front of the fixed cylinder 15. The top of the fixed frame 14 is fixedly connected to the bottom of the floating boat 1. A square slot 141 is opened at the bottom of the fixed frame 14. The cover plate 132 is removed from the protective cover 131, and then the nut 342 is removed to release the fixation of the protective cover 131. Then the protective cover 131 is pulled upward so that the diamond-shaped spring piece 351 on the square rod 135 is inserted into the square slot 141. The diamond-shaped spring piece 351 is elastic and can pass smoothly through the fixed frame 14. At this time, the square rod 135 enters into the square slot 141. Then the protective cover 131 is released, and the diamond-shaped spring piece 351 supports the protective cover 131, which facilitates the maintenance of the ammonia nitrogen detector 331 by the staff.

[0028] A square rod 135 is fixedly connected to the top of the protective cover 131, and a diamond-shaped spring piece 351 is fixedly connected to the top of the square rod 135. The square rod 135 is compatible with the square slot 141. When the diamond-shaped spring piece 351 is inserted into or detached from the fixing frame 14, it can be pulled with force. Since the diamond-shaped spring piece 351 is elastic, it can be successfully detached.

[0029] The fixed cylinder 15 is equipped with an internal threaded rod 152, which is internally threaded with a threaded rod 151. The bottom of the internal threaded rod 152 is fixedly connected to the top of the connecting block 133. By rotating the threaded rod 151 forward or backward, the lifting and lowering of the internal threaded rod 152 can be controlled, thereby adjusting the depth of the ammonia nitrogen detector 331. This allows for the detection of water environments at different depths, meeting different detection needs.

[0030] Inside the shield 12, there is a fixed seat 121. The bottom of the fixed seat 121 is fixedly connected to the top of the floating boat 1. A motor 122 is fixedly connected to the top of the fixed seat 121. A gear 123 is fixedly connected to the bottom output end of the motor 122. A gear 124 is meshed with the front of the gear 123. A stabilizing frame 125 is provided in front of the fixed seat 121. The bottom of the stabilizing frame 125 is fixedly connected to the top of the floating boat 1. When the motor 122 is started, it drives the gear 123 to rotate. The gear 123 will drive the threaded rod 151 to rotate through the gear 124, and control the threaded rod 151 to rotate forward or backward.

[0031] The top of the threaded rod 151 passes through the stabilizer 125 and extends to the bottom of the gear 124 for fixed connection. The top of the threaded rod 151 is rotatably connected to the center of the stabilizer 125. Three protrusions 153 are fixedly connected to the outer surface of the internal threaded rod 152. Limiting strips 154 are slidably connected to both sides of the three protrusions 153. The side of the limiting strip 154 ​​away from the internal threaded rod 152 is fixedly connected to the inner wall of the fixed cylinder 15. Since the protrusions 153 are limited by the limiting strips 154, the internal threaded rod 152 can move in a straight line when it moves, avoiding slippage.

[0032] One specific application of this embodiment is:

[0033] In use, pull the protective cover 131 downwards to disengage the diamond-shaped spring piece 351 on the square rod 135 from the fixing frame 14. The initial position of the protective cover 131 is above the ammonia nitrogen detector 331, and the square rod 135 is inserted into the square slot 141 on the fixing frame 14. The diamond-shaped spring piece 351 is above the square slot 141 to support the protective cover 131. Then, the protective cover 131 moves downwards until it contacts the limiting ring 134, and the threaded shaft 341 is inserted into the protective cover 131. Then, install the nut 342 on the threaded shaft 341 to fix the protective cover 131. Finally, connect the cover plate 132 to the bottom of the protective cover 131 by thread. The handle 321 facilitates the installation and removal of the cover plate 132. After installation, the floating boat 1 is placed on the water surface, and the protective cover 131 and the ammonia nitrogen detector 331 enter the water. Under the action of the controller 11, the propeller 2 is started, making the floating boat 1 move on the water surface. The protective cover 131 and the cover plate 132 are used to protect the ammonia nitrogen detector 331, preventing branches or stones from directly colliding with the ammonia nitrogen detector 331, effectively protecting the ammonia nitrogen detector 331 from damage. At the same time, the water flow will flow through several openings on the protective cover 131 and the cover plate 132, so as not to affect the ammonia nitrogen detector 331's detection of the water environment.

[0034] When it is necessary to detect water environments at different depths, the motor 122 is started to drive the gear 123 to rotate. The gear 123 then drives the threaded rod 151 to rotate through the gear 124. The internal threaded rod 152 will then move up or down. Since the protrusion 153 is limited by the limiting strip 154, the internal threaded rod 152 can move in a straight line. By rotating the threaded rod 151 forward or backward, the lifting and lowering of the internal threaded rod 152 can be controlled, thereby adjusting the depth of the ammonia nitrogen detector 331, so that water environments at different depths can be detected.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
