Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , one kind horizontal unit packing case water retaining device is shown in the drawing, including water retaining structure 1, water retaining structure 1 includes semicircle ring 101 and semicircle plate 103, semicircle plate 103 both sides sidewall are fixedly connected with semicircle ring 101, the outer circle side of semicircle ring 101 is fixedly connected with a plurality of rectangular hole fixing pieces 104, a plurality of rectangular hole fixing pieces 104 are evenly distributed in semicircle ring;Semicircle ring 101 both ends are connected with unfolding structure 2 through detachable structure 3.

[0021] It is worth noting that by increasing water retaining structure 1 can cover the water pump packing area, play a covering role, semicircle ring 101 is arranged at the bottom of the water pump packing, when the packing wears or ages, the shaft sleeve wears or the shaft appears eccentric, the packing gland is too loose or fastening is uneven, and the cooling medium pressure is too high, the packing water drop may be excessive or overflow, thereby flowing into the inner ring bottom of semicircle ring 101, reducing the possibility of surrounding environment pollution, unfolding structure 2 is regularly opened to check the internal water seepage, if the water seepage is large, the packing box related components or packing are replaced in time, the covering mode is adopted, not only can effectively avoid the environmental pollution caused by the overflow of packing water drop, but also can facilitate the regular inspection and maintenance of internal water seepage by staff, specifically, the design of unfolding structure 2 enables staff to easily open and check the situation inside water retaining structure 1, without disassembling the whole water retaining device, improving the work efficiency.

[0022] Please refer to Figure 1 and Figure 2 , the unfolding structure 2 includes quarter circle ring 201 and quarter circle plate 202, quarter circle plate 202 both sides are fixedly connected with quarter circle ring 201, quarter circle ring 201 and the outer wall of semicircle ring 101 are close to each other, this design enables unfolding structure 2 to be stably connected on water retaining structure 1, and facilitates opening and closing, when it is necessary to check the internal situation of water retaining structure 1, staff only need to operate quarter circle plate 202, make it drive quarter circle ring 201 move along the outer wall of semicircle ring 101, thereby opening the top of water retaining structure 1, facilitating observation and maintenance.

[0023] Please refer to Figure 1and Figure 2 The reinforcing block 102 is fixedly connected to the side of the rectangular hole fixing part 104 close to the semicircular plate 103, and the bottom side of the reinforcing block 102 is fixedly connected to the outer circular side wall of the semicircular ring 101. The design of the reinforcing block 102 not only enhances the connection strength between the rectangular hole fixing part 104 and the semicircular ring 101, but also makes the entire water retaining structure 1 more stable and durable.

[0024] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the detachable structure 3 includes an L-shaped elastic plate 301 and a plug rod 304. The quarter circular ring 201 is fixedly connected to the L-shaped elastic plate 301 close to one end of the semicircular ring 101. The semicircular ring 101 is fixedly connected to a sleeve ring 303 at both ends. The horizontal end of the L-shaped elastic plate 301 is fixedly connected to the plug rod 304, and the other end of the plug rod 304 is inserted into the sleeve ring 303.

[0025] The connection mode of the L-shaped elastic plate 301 and the quarter circular ring 201 enables the detachable structure 3 to be stably installed on the water retaining structure 1. The cooperation design of the plug rod 304 and the sleeve ring 303 further enhances the stability of the structure.

This design not only facilitates maintenance and replacement of parts, but also improves work efficiency.

[0026] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the two quarter circular rings 201 are provided with installation structures 4 at adjacent ends. The installation structure 4 includes an L-shaped hole fixing part 403. The outer circular side walls of the two quarter circular rings 201 are fixedly connected to the L-shaped hole fixing part 403. The two L-shaped hole fixing parts 403 are symmetrically arranged and connected to the corresponding internal thread sleeve 401 through the bolt 402.

[0027] Notably, the design of the L-shaped hole fixing part 403 enables the two quarter circular rings 201 to be tightly connected together to form a complete circular ring structure, enhancing the structural strength of the water retaining device.

[0030] Working principle: when the filler is worn out, aged or the shaft sleeve is worn out, the shaft is eccentric, the filler cover is loose, the fastening is uneven, and the cooling medium pressure is too high, etc., causing excessive dripping or overflow, the dripping water will be collected at the bottom of the inner ring of the semicircular ring 101, thereby reducing the possibility of surrounding environmental pollution. The unfolded structure 2 is composed of the quarter circular ring 201 and the quarter circular plate 202, and is connected with the water blocking structure 1 through the detachable structure 3. When it is necessary to check the internal water seepage of the water blocking structure 1, the staff can operate the quarter circular plate 202 to drive the quarter circular ring 201 to move along the outer wall of the semicircular ring 101, so as to open the top of the water blocking structure 1, thereby facilitating the observation and maintenance of the inside. The whole water blocking device aims to timely leak stopping for a small amount of leakage. The inner diameter of the whole water blocking device is much larger than the outer diameter of the filler basket. Since the seepage water always flows from high to low, it always leaks to the bottom of the inner arc surface of the semicircular ring 101. The height of the water liquid surface should be controlled at the horizontal end of the semicircular ring 101, and it is necessary to be cleaned regularly. The design mainly aims to timely leak stopping and checking whether the filler basket needs to be replaced due to aging, so as to prevent pollution and reduce the frequency of regular cleaning.
