Description

Technical Field

[0001] This utility model relates to the field of automatic pH adjustment, specifically to an automatic pH adjustment device for aquaculture water in a recirculating aquaculture pond. Background Technology

[0002] The pH value of the water in recirculating aquaculture ponds has a crucial impact on the health and growth of fish and other aquatic organisms. The ideal pH range is usually between 7.0 and 8.5, depending on the specific needs of the species being cultured. When the pH is too low, it will not only inhibit the normal physiological functions of fish, such as reduced respiratory efficiency and impaired immune system, but may also increase the toxicity of harmful substances such as ammonia nitrogen, leading to poisoning symptoms in fish. Conversely, if the pH is too high, it is easy to cause calcium carbonate precipitation, which will interfere with the normal functioning of fish gills and even cause skin burns. In addition, an unsuitable pH level will also directly affect the structure and activity of the microbial community in the water, thereby interfering with the material cycling process in the entire ecosystem. For example, nitrifying bacteria will not be able to effectively convert ammonia nitrogen into a harmless form, ultimately affecting water quality management and disease control. Therefore, regularly monitoring and adjusting the pH value to a suitable range in daily management is one of the key factors to ensure the success of recirculating aquaculture.

[0003] In the existing technology, traditional pH adjustment devices mainly consist of a pH sensor, a medicine tank, and a fixing device. The pH sensor can accurately measure the pH value of the aquaculture pond water. If the pH value of the water exceeds the range, the operator manually operates the medicine tank to adjust the pH value of the water, thereby maintaining the stability of the pH value of the water.

[0004] However, when using traditional pH adjustment devices for recirculating aquaculture ponds, it is necessary to manually add chemicals when the pH value of the water exceeds the specified value. This manual intervention not only increases the labor intensity but may also cause water quality fluctuations due to untimely response or improper dosage control, thereby affecting the health and growth of the cultured organisms. To address this issue, this invention proposes an automatic pH adjustment device for recirculating aquaculture ponds to solve the aforementioned technical problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The automatic pH adjustment device for circulating water aquaculture ponds proposed in this utility model can be used by fixing the frame to a suitable position with a fixing plate, and then placing the pH sensor and discharge pipe in the aquaculture pond.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: an automatic pH adjustment device for a recirculating aquaculture pond, the automatic pH adjustment device for a recirculating aquaculture pond includes: a central control device 1, a pH sensor 2 connected below the central control device 1, self-priming pumps 3 connected on both sides of the central control device 1, and a discharge pipe 4 connected to one end of the self-priming pump 3.

[0025] The fixing frame 5 has a rectangular structure, and fixing plates 6 are provided at both ends of the back of the fixing frame 5.

[0026] In use, the fixing frame 5 can be fixed to a suitable position using the fixing plate 6. Then, the pH sensor 2 and the discharge pipe 4 in the device are placed in the aquaculture pond. The device can adjust the preset pH range. When the pH sensor 2 detects that the pH exceeds this range, the central control device 1 will automatically start the self-priming pump 3 on one side and release the appropriate medicine into the aquaculture pond through the discharge pipe 4 to maintain the pH value of the water in the aquaculture pond within a stable range. This avoids damage to the aquatic environment caused by improper manual adjustment of the pH value of the aquaculture water, and also reduces the intensity of manual labor.

[0027] Example 2: Based on Example 1, in order to enable the device to automatically adjust the pH value of the aquaculture water, a central control device 1 is equipped with a transmission line 7 installed at the bottom. The pH sensor 2 is connected to the central control device 1 through the transmission line 7. The central control device 1 is installed behind the display screen 8. Two sets of self-priming pumps 3 are provided. One end of the self-priming pump 3 is equipped with a suction tube 16, and the other end of the suction tube 16 is placed in the medicine tank 9. The medicine tank 9 has a hole on the top, and a sealing plug 10 is installed in the hole. During use, the operator can adjust the normal range of the pH value by adjusting the adjustment button 13. The pH sensor 2 of the device is placed in the water, and the detected data is transmitted to the central control device 1 through the transmission line 7. When the pH value exceeds the range, the central control device 1 controls the self-priming pump 3 to draw the medicine in the medicine tank 9, and then applies it to the aquaculture water through the discharge pipe 4, thereby realizing automatic adjustment of the pH value.

[0028] One end of the discharge pipe 4 is fixedly connected to one end of the surface of the self-priming pump 3, and the other end of the discharge pipe 4 is equipped with a high-pressure water gun 11. Multiple thin tubes 12 are installed on the surface of the high-pressure water gun 11. A display screen 8 is installed on the surface of the fixed frame 5, and multiple adjustment buttons 13 are installed below the display screen 8. A cover plate 14 is installed on the top of the fixed frame 5. A hole is opened on the surface of the fixed plate 6, and a fixing screw 15 is installed in the hole. In order to avoid uneven application range and slow diffusion speed of medicine when automatically adjusting pH value, the synergistic effect of the high-pressure water gun 11 and the thin tubes 12 at one end of the discharge pipe 4 can expand the application range of medicine and make it easier to diffuse.

[0029] Example 3: Based on Example 2, a cover plate 14 is provided to prevent water from entering the device and damaging internal components. The cover plate 14 is a square plate structure. A waterproof sheet 17 is provided below the cover plate 14. The lower surface of the waterproof sheet 17 has a rectangular protrusion, and the side of the protrusion corresponds to the inner wall of the fixing frame 5. A hole is opened at the corner of the cover plate 14, and a fixing screw 15 is installed in the hole. The waterproof structure of the device has two layers. The cover plate 14 can provide initial waterproofing for the device, while the waterproof sheet 17 below the cover plate 14 can provide secondary waterproofing for the inside of the device, preventing water from entering the device and damaging it, and increasing the service life of the device.

[0030] In actual use, the fixing frame 5 can be fixed to a suitable position by fixing plate 6, and then the pH sensor 2 and discharge pipe 4 in the device can be placed in the aquaculture pond. The device can adjust the preset pH range. When the pH sensor 2 detects that it exceeds this range, the central control device 1 will automatically start the self-priming pump 3 on one side and put the appropriate medicine into the aquaculture pond through the discharge pipe 4 to maintain the pH value of the water in the aquaculture pond stable within a range. This avoids damage to the aquatic environment caused by improper manual adjustment of the pH value of the aquaculture water, and also reduces the intensity of manual labor.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
