The first operating member 31 is connected to the second rod section 2, and the second operating member 32 is arranged on the first operating member 31 and can rotate relative to the first operating member 31.

[0029] Specifically, when adjusting the valve, the second operating member 32 is rotated so that an angle is formed between the second operating member 32 and the first operating member 31, so that the valve adjustment is convenient. When the valve is not adjusted, the second operating member 32 is rotated so that the second operating member 32 and the first operating member 31 overlap, so as to reduce the space occupied by the operating assembly 3, so as to facilitate the storage of the device.

[0030] In the device for draining a water tank valve of the utility model embodiment, the second rod segment 2 can move relative to the first rod segment 1 along the extension direction of the first rod segment 1, so that the overall length of the second rod segment 2 and the first rod segment 1 can be adjusted, and the operating component 3 is arranged on the second rod segment 2. The valve is adjusted by the operating component 3, so that the operator does not need to frequently cross the belt, which not only makes the operation simple for the operator, but also ensures the safety of the operator and improves the applicability of the device for draining a water tank valve of the utility model embodiment.

[0031] In the related art, in order to facilitate operators to operate the valves, a bridge belt is arranged at each water tank so that the operators can adjust the valves through the bridge belt. This method greatly increases the workload and cost. However, the device for draining water from a water tank in the embodiment of the utility model can not only reduce the number of bridge belts to be installed, but also improve the efficiency of valve operation.

[0032] In some embodiments, the first rod segment 1 has a first channel 11 and a socket 12. The first channel 11 is connected to one end of the first rod segment 1 (such as Figure 1 The right end of the first rod segment 1 shown in FIG. 1 ) is directed toward the other end of the first rod segment 1 (as shown in FIG. Figure 1 The insertion hole 12 is provided on the outer circumference of the first rod segment 1 and is connected to the first channel 11. One end of the second rod segment 2 is inserted into the first channel 11, and the second rod segment 2 has a plurality of openings 21, which are arranged at intervals along the extension direction of the second rod segment 2. Specifically, the first rod segment 1 extends in the left-right direction, and the insertion hole 12 is located at the right end of the first rod segment 1.

[0033] The device for draining the water tank also includes a first limit member 4, which is arranged on the first rod section 1 and at least part of the first limit member 4 is located in the first channel 11 through the socket 12, and at least part of the first limit member 4 passes through the socket 12 and the opening 21 in sequence.

[0034] Specifically, when the opening 21 on the second rod segment 2 corresponds to the through hole on the first rod segment 1, the first limiting member 4 passes through the insertion hole 12 and the opening 21 in sequence to limit the second rod segment 2, so that the second rod segment 2 is firmly connected to the first rod segment 1 and is not easy to separate, thereby improving the reliability of the device for draining the water tank of the utility model embodiment when in use.

[0035] In some embodiments, the first limiting member 4 includes a first plug rod 41, a limiting rod 42 and a first elastic member 43. The limiting rod 42 is arranged at one end of the first plug rod 41. The extension direction of the limiting rod 42 forms an angle with the extension direction of the first plug rod 41. At least a portion of the other end of the first plug rod 41 extends into the insertion hole 12. The first elastic member 43 is wrapped around the first plug rod 41. One end of the first elastic member 43 is connected to the outer peripheral surface of the first rod segment 1, and the other end of the first elastic member 43 is connected to the limiting rod 42.

[0036] Specifically, the extension direction of the limit rod 42 is orthogonal to the extension direction of the first insertion rod 41. The first elastic member 43 is located between the limit rod and the first rod segment 1. When the first limit rod 4 is in use, the limit rod 42 is pulled to make the other end of the first insertion rod 41 outside the insertion hole 12. At this time, the first elastic member 43 has elastic force. After adjusting one of the openings 21 on the second rod segment 2 to correspond to the insertion hole 12, the limit rod 42 is loosened. The first insertion rod 41 is inserted into the insertion hole 12 and the opening 21 in turn under the elastic force of the first elastic member 43 to limit the second rod segment 2. Therefore, the first limit rod 4 is easy to operate when in use, so that the adjustment method between the first rod segment 1 and the second rod segment 2 is simple and convenient.

Specifically, when the second operating member 32 is located at the second position 34, the support assembly 5 is used to support the fourth section 321 and the first section 311, so that the fourth section 321 and the first section 311 remain in an open state and are not easy to rotate.

[0045] In some embodiments, the support assembly 5 includes a connecting rod 51 and a slider 52, one end of the connecting rod 51 is connected to the second operating member 32, and the other end of the connecting rod 51 is connected to the slider 52, and the slider 52 is slidably installed on the first section 311.
