[0033] Example 1.

[0034] like Figure 1-10 As shown, the present invention provides a crayfish temporary holding device, including several stackable holding boxes 3, an installation mechanism inside the holding boxes 3, a detachable shielding mechanism on the installation mechanism, a detachable top cover 4 on the top of the holding boxes 3, a feeding mechanism rotatably mounted on the holding boxes 3 for feeding and observing the crayfish, and a connecting mechanism mounted on the holding boxes 3 and connected to the holding boxes 3 for connecting two adjacent holding boxes 3; ventilation holes 5 are evenly distributed on the holding boxes 3 and the top cover 4, and the connecting mechanism is provided with an inlet 1 and an outlet 2 connected to the holding boxes 3.

[0035] In this invention, the temporary holding device consists of multiple independent holding boxes 3. These boxes 3 can be stacked or used individually, thus reducing the installation space required and facilitating the temporary holding of crayfish. The shielding mechanism is detachably mounted on the mounting mechanism, providing crayfish with a place to climb and be sheltered, thereby reducing the risk of fighting among them. The top cover 4 is detachably fixed to the top of the holding box 3 using screws or clips. The top cover 4 effectively prevents crayfish from escaping and also facilitates their release. The feeding mechanism is rotatably mounted on the holding box 3, allowing for easy feeding of the crayfish and observation of their growth. Ventilation holes 5 are evenly distributed on the holding box 3 and the top cover 4, ensuring air circulation within the holding box 3 and guaranteeing normal oxygen exchange for the crayfish during temporary holding.

[0036] In this utility model, the connecting mechanism facilitates the assembly and fixing of two adjacent temporary holding tanks 3. The inlet 1 and outlet 2 are located on the temporary holding tank 3 and connected to the connecting sleeve 6. Specifically, the connecting sleeve 6 is connected to an external water inlet pipe (not shown in the figure), which has an inlet valve (not shown in the figure). The connecting sleeve 6 has an outlet pipe connected to the outlet 2, which is connected to an external drainage main pipe. A drainage channel is formed inside the connecting sleeve 6, and a drainage valve (not shown in the figure) is located on the connecting sleeve 6 and connected to the drainage channel. Simultaneously, an overflow outlet 23 is located on the temporary holding tank 3 and connected to the connecting sleeve 6. The 6 is equipped with an overflow valve (not shown in the figure) connected to the drainage channel. The overflow valve is located above the drain valve. When water needs to be added to the temporary holding tank 3, the drain valve on the drainage channel is closed and the inlet valve is opened. The water in the external water inlet pipe enters the connecting mechanism through the inlet pipe and inlet 1. Since the connecting mechanism is connected to the temporary holding tank 3, the water can enter the temporary holding tank 3. When drainage is needed, the drain valve on the drainage channel is opened and the overflow valve (not shown in the figure) is closed. The water in the temporary holding tank 3 is discharged from the temporary holding tank 3 through the outlet 2, the drainage channel and the outlet pipe, thereby ensuring the circulation and renewal of the water in the temporary holding tank 3.

[0037] Example 2.

[0038] like Figure 1-10 As shown, the present invention provides a crayfish temporary holding device, including several stackable holding boxes 3, an installation mechanism inside the holding boxes 3, a detachable shielding mechanism on the installation mechanism, a detachable top cover 4 on the top of the holding boxes 3, a feeding mechanism rotatably mounted on the holding boxes 3 for feeding and observing the crayfish, and a connecting mechanism mounted on the holding boxes 3 and connected to the holding boxes 3 for connecting two adjacent holding boxes 3; ventilation holes 5 are evenly distributed on the holding boxes 3 and the top cover 4, and the connecting mechanism is provided with an inlet 1 and an outlet 2 connected to the holding boxes 3.

The inlet 1 and the outlet 2 are disposed in the connecting sleeve 6 and connected to the temporary holding tank 3. When two temporary holding tanks 3 are stacked, the connecting post 7 on one temporary holding tank 3 is located in the connecting sleeve 6 on the other temporary holding tank 3.

[0040] In this embodiment 2, four connecting sleeves 6 are provided. The four connecting sleeves 6 are respectively installed on the outer wall of the temporary holding box 3, and the connecting sleeves 6 are provided with drainage channels that communicate with the bottom of the temporary holding box 3. The connecting column 7 is connected to the bottom of the temporary holding box 3 by threads. At the same time, the sealing ring 17 can seal the connection between the connecting column 7 and the connecting sleeve 6, thereby preventing water from flowing out of the connecting sleeve 6 and preventing water leakage from the connecting column 7 after connection.

[0041] When two adjacent temporary storage boxes 3 are stacked, the one at the bottom is temporary storage box A, and the one at the top is temporary storage box B. The connecting post 7 is threaded to the bottom of the connecting sleeve 6 on the temporary storage box B. Then, the connecting post 7 is aligned with the connecting sleeve 6 on the temporary storage box A, and the connecting post 7 is inserted into the connecting sleeve 6 on the temporary storage box A. This completes the assembly of the two temporary storage boxes 3. The cooperation between the connecting post 7 and the connecting sleeve 6 facilitates the stacking of two adjacent temporary storage boxes 3 and also prevents the temporary storage boxes 3 from tilting after assembly.

[0042] The connecting sleeve 6 is provided with a water inlet channel that communicates with the temporary holding tank 3; the connecting sleeve 6 is provided with a drain pipe (not shown in the figure) that communicates with the external drainage main pipe; the connecting sleeve 6 is provided with a water outlet pipe (not shown in the figure) that communicates with the water outlet 2; when it is necessary to add water to the temporary holding tank 3, the drain valve is closed, the water inlet 1 is connected to the external water inlet pipe, the water in the water inlet pipe enters the connecting sleeve 6 through the water inlet 1, and the water in the connecting sleeve 6 enters the temporary holding tank 3 through the water inlet channel; when it is necessary to drain, the drain valve on the drain channel is opened, the overflow valve (not shown in the figure) is closed, and the water in the temporary holding tank 3 is discharged from the temporary holding tank 3 through the water outlet 2 and the water outlet pipe, thereby ensuring the circulation and renewal of the water in the temporary holding tank 3.

The inlet 1 and the outlet 2 are disposed in the connecting sleeve 6 and connected to the temporary holding tank 3. When two temporary holding tanks 3 are stacked, the connecting post 7 on one temporary holding tank 3 is located in the connecting sleeve 6 on the other temporary holding tank 3.

[0046] The connecting sleeve 6 is provided with an overflow port 23.

[0047] In this embodiment 3, the overflow outlet 23 is located above the outlet 2. The overflow outlet 23 is located between the connecting sleeve 6 and the temporary holding tank 3, connecting the connecting sleeve 6 and the temporary holding tank 3. When the water flow in the temporary holding tank 3 is higher than the overflow outlet 23, the excess water will enter the connecting sleeve 6 through the overflow channel. The water in the connecting sleeve 6 will be discharged into the main drainage pipe through the outlet pipe, thereby facilitating the control of the water depth in the temporary holding tank 3, which is convenient for the breeding of crayfish.

[0075] Working principle

[0076] When using a single holding box 3 for breeding, place the holding box 3 in the holding area, fix the cover 16 to the limiting post 18 with buckles or bolts, put the crayfish into the holding box 3, and after the release, put the top cover 4 on the top of the holding box 3; when feeding, simply open the transparent feeding window 11 to feed the crayfish.

[0077] When multiple temporary holding devices are used in combination, the connecting column 7 is threaded to the bottom of the connecting sleeve 6 on the temporary holding box B. The temporary holding box B is placed in the stacking groove 8 so that the connecting column 7 is aligned with the connecting sleeve 6 on the temporary holding box A. The connecting column 7 is then inserted into the connecting sleeve 6 on the temporary holding box A to complete the assembly of the two temporary holding boxes 3. When releasing crayfish, the transparent feeding window 11 is opened to release the crayfish into the corresponding temporary holding box 3. Feeding is also done through the transparent feeding window 11, which facilitates the breeding of crayfish.

[0078] When water needs to be added to the temporary holding tank 3, close the drain valve (not shown in the figure), connect the inlet pipe to the external main water inlet pipe, and open the inlet valve on the inlet pipe. The water in the main water inlet pipe enters the temporary holding tank 3 through the inlet pipe, inlet 1, connecting sleeve 6, and inlet channel. When the water in the temporary holding tank 3 overflows into the main drain pipe through the overflow outlet 23, close the inlet valve to complete the water filling of the temporary holding tank 3. Similarly, when drainage is required, open the drain valve and close the overflow valve. The water in the temporary holding tank 3 enters the drainage channel through the outlet 2, and flows into the main drain pipe through the connecting sleeve 6 and outlet pipe, thereby ensuring the circulation and renewal of water in the temporary holding tank 3.
