Problems solved by technology

Mechanical desilting mainly uses hydraulic pond dredging units to remove the silt at the bottom of the water body. This method cannot achieve the reuse of nutrients in the bottom mud; although the microbial method improves the resource utilization of nutrient-rich substances in the bottom mud, it is difficult to The effect of controlling the growth of microorganisms is good and bad; although the chemical method is quick, it is easy to cause chemical pollution, which is transmitted to consumers who eat aquatic animals, and there are many problems

Embodiment 1

[0025] Such as figure 1 , 2 As shown, a walking type tank bottom dirt monitoring device for shrimp culture ponds includes a floating body 1 suspended on the water surface line 2, a propeller 3 is connected to the bottom of the floating body 1, and a supporting frame 4 is connected to the lower part of the floating body 1. Below the frame 4 is connected a monitoring assembly 7 for monitoring the distribution of dirt 8 on the pool bottom 6 through a telescopic rod 5 . In the process of monitoring the distribution of the dirt 8 at the bottom of the culture pond, the propeller 3 is remotely controlled by the industrial computer to drive the floating body 1 to move in a navigable manner in the culture pond. The route and speed are all controlled by the industrial computer to the propeller 3. The position monitors the distribution of the dirt 8 on the bottom 6 of the culture pond, and adjusts the distance between the monitoring component 7 and the dirt 8 on the bottom 6 of the pool...

Embodiment 2

[0029] Such as Figure 4 , 5 As shown, the further optimization scheme of this embodiment on the basis of Embodiment 1 is: the blades 301 of the propeller 3 are evenly distributed with guide vanes 302 . By setting guide vanes 302 on the blades 301, the propeller 3 can keep the flow of water flowing smoothly during operation, which is beneficial to the stability of the flow field around the propeller 3, and prevents the contamination of the bottom 6 of the culture pond due to the work of the propeller 3 during monitoring. The resuspension of object 8 affects the accuracy of monitoring data.

[0030] The guide vane 302 is formed by the intersection of two right triangular bodies, the included angle is preferably 123°, and the ratio of the length K2 of the base of the triangular body to the height K1 of the triangular body is preferably 1.28:1. The data of tens of thousands of scientific experiments have proved that when the ratio of K2 to K1 is 1.25~1.30:1, the water flow arou...

Embodiment 3

[0034] Such as image 3 As shown, the further optimization scheme of this embodiment on the basis of Embodiment 1 is: the protection mechanism 9 includes a first protection plate 905 connected to the side of the connection plate 701, and the end of the first protection plate 905 is connected with a rotatable joint through a connection block 906. The second protective plate 907 of the first protective plate 905 is provided with an electromagnet 904, the electromagnet 904 is connected with a spring 901, and the end of the spring 901 is connected with a magnetic ball 902, between the magnetic ball 902 and the second protective plate 907 A connecting rope 903 is connected. The angle between the second protective plate 907 and the first protective plate 905 is adjusted by the power on and off of the electromagnet 904 controlled by the industrial computer. Adsorption shortens the distance between the electromagnet 904 and the magnetic ball 902, changes the angle of the connecting r...

Abstract

The invention discloses a walking bottom sewage monitoring device for shrimp culture ponds, wherein the device belongs to the field of culture pond monitoring. The device comprises a floating body which is connected with a propeller at the bottom of the floating body. A support frame is connected with the lower part of the floating body. and a monitoring component for monitoring the distribution of dirt on the bottom of the ponds is connected with a support frame below the support frame through a telescopic rod. The invention utilizes the walking navigation type to monitor the bottom sewage condition at any position in the aquaculture pond, monitors the bottom quality condition of the aquaculture pond in real time and accurately obtains the bottom quality monitoring data.

Description

technical field [0001] The invention belongs to the technical field of culture pond monitoring, and in particular relates to a walking type pond bottom dirt monitoring device for shrimp culture ponds. Background technique [0002] To raise fish, raise water first, and clear water is difficult for fish to live. Most of the pond farming in my country adopts the traditional farming method, and the farmers are one-sidedly pursuing economic benefits, and often need to invest a lot of feed and fertilizer in the breeding process. Most of these substances are deposited to the bottom of the pond in the form of fish and shrimp feces and residual bait to form the substrate. Because the decomposition of organic substances in the substrate requires a large amount of oxygen, an anoxic and anaerobic environment will be generated at the bottom of the pond, seriously affecting At the same time, a large amount of nutrients such as nitrogen and phosphorus contained in the substrate cannot ret...
