[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0031] Please refer to the attached Figure 1 To the attached Figure 7 The utility model is described as follows: a water injection device and a water injection system.

[0032] The utility model proposes a water injection device, such as Figure 1 and Figure 2 As shown, the water injection device includes a support 1 and a bracket 2 arranged on the support 1. The support 1 is also provided with a water injection valve 3, which is used to control the water injection flow rate. It also includes a locking rod 4. A guide sleeve is provided at the switch of the water injection valve 3. The locking rod 4 is passed through the guide sleeve and the bracket 2 to control the opening and closing of the water injection valve 3. A lock hole is provided at one end of the locking rod 4, and the lock hole is elastically connected to the bracket 2 through a connecting rope. A limiting portion is provided at the other end, and the limiting portion can abut against the bracket to limit the position of the locking rod.

[0033] The water injection device uses a locking rod 4 to extend into the switch of the water injection valve 3 and the locking hole 41 of the first mounting piece 51 to achieve locking and closing of the water injection valve 3. At the same time, the locking hole 41 at the end of the locking rod 4 is used to achieve an elastic connection with the first mounting piece 51 through the connecting rope 6, thereby preventing the valve switch from being in an open state due to external factors when exposed to seawater impact or underwater surge. In addition, the elastic connection method of the connecting rope 6 is softer, thereby avoiding rigid contact between the locking rod 4 and the first mounting piece 51. On the basis of ensuring the stability of the water injection device, it can play a certain buffering role for the device.

[0034] Specifically, if Figure 2 and Figure 3 As shown, the connecting rope 6 can be a spring coil, and the material can be rubber, flexible plastic, etc.

[0035] Furthermore, the bracket includes a first mounting plate 51, which is provided with a fixing protrusion, and a connecting hole is provided in the fixing protrusion. The connecting hole of the fixing protrusion is elastically connected to the locking hole 41 of the locking rod 4 via a connecting rope 6. The provision of the fixing protrusion on the first mounting plate 51 realizes the connection between the first mounting plate 51 and the locking rod 4, ensures the stability of the first mounting plate 51, prevents the first mounting plate 51 from being damaged by pulling due to insufficient stress, and further ensures the safety of the water injection device.

[0036] More preferably, Figure 2 and Figure 4 As shown, the fixing protrusion is defined as a fixing rod 511, which extends in the same direction as the locking rod 4. A connecting hole is provided at the end of the fixing rod 511 away from the first mounting plate 51. The connecting hole of the fixing rod 511 is elastically connected to the locking hole 41 of the locking rod 4 via a connecting rope 6. This structure, which utilizes the fixing rod 511, which is parallel to the locking rod 4, to connect the locking hole 41, improves the balance between the first mounting plate 51 and the locking rod 4 while ensuring the stability of the first mounting plate 51.

[0037] Further, if Figure 2As shown, the bracket 2 further includes a second mounting piece 52, which is spaced apart from the first mounting piece 51. The locking rod 4 is sequentially inserted through the second mounting piece 52, the guide sleeve at the switch position of the water injection valve 3, and the first mounting piece 51, and is connected to the first mounting piece 51 via a connecting rope 6. By providing the second mounting piece 52, the locking rod 4 is sequentially inserted through the second mounting piece 52, the switch position of the water injection valve 3, and the first mounting piece 51, thereby ensuring the support effect of the locking rod 4 and further improving the stability of the water injection device.

[0038] Furthermore, if Figure 2 As shown, the limiting portion 42 can abut against the second mounting piece 52 to limit the position of the locking rod 4. The limiting portion 42 is used to limit the position of the locking rod 4, thereby ensuring the connection effect between the locking rod 4 and the first mounting piece 51.

[0039] Furthermore, if Figure 2 As shown, a lug 43 is provided at the other end of the locking rod 4, away from the locking hole 41. The lug 43 and the locking rod 4 form a T-shape, and the stopper 42 is located between the lug 43 and the locking hole 41. The provision of the lug 43 at the other end of the locking rod 4 prevents over-insertion of the locking rod 4 due to failure of the stopper 42, thereby providing a secondary safety for the device.

[0040] In this embodiment, if Figure 1 、 Figure 5 and Figure 6 As shown, the first mounting piece 51 and the second mounting piece 52 have the same shape, both including a right-angled surface 531 and a semicircular surface 532. The right-angled surface 531 is used to connect to the bracket 2 to provide better support for the device. The semicircular surface 532 is provided on the side of the right-angled surface 531 not connected to the bracket 2 and is provided with a through hole for plugging and mating with the end of the locking rod 4 provided with the locking hole 41. In other embodiments, the shapes of the first mounting piece 51 and the second mounting piece 52 can also be other structures, which are not specifically limited here.

[0041] Furthermore, if Figure 2 and Figure 4 As shown, the bracket 2 includes a top beam 21, which is polygonal. A support beam 22 is provided at the corner of the top beam 21. The support beam 22 is provided at an angle to the frame of the top beam 21 and is connected to the support 1 to provide support for the top beam 21.

[0042] Furthermore, if Figure 2 and Figure 4As shown, the bracket 2 also includes a bottom beam 23. The bottom beam 23 has the same shape as the top beam 21 and is arranged parallel to the top beam 21 in the vertical direction. The bottom beam 23 is located between the top beam 21 and the support 1, and the corners of the bottom beam 23 are connected to the support beam 22. The bottom beam 23, the top beam 21 and the support beam 22 enclose a storage space, and the water injection valve 3 is arranged in the storage space. The water injection valve 3 is arranged in the storage space to provide protection for the water injection valve 3.

[0043] Specifically, if Figure 2 and Figure 4 As shown, the bottom beam 23 and the top beam 21 are arranged in a rectangular shape, and the support beam 22 is not only arranged at the corners of the bottom beam 23 and the top beam 21, but also connected to the edges of the top beam 21 and the bottom beam 23, thereby improving the stability of the device.

[0044] Furthermore, if Figure 1 As shown, the side of the support 1 connected to the support beam 22 and the water injection valve 3 is set to a curved surface, and the support beam 22 and the water injection valve 3 are connected to the support 1 through the base 24.

[0045] Specifically, the base 24 is made of a flexible material.

[0046] The present invention also provides a water injection system comprising the aforementioned water injection device, wherein the water injection valve contacts seawater to provide a water source. The water injection system utilizes the water injection valve to contact seawater to provide a water source for water injection. The water injection device has the advantage of a simple structure, allowing workers to assemble it on-site and then perform underwater operations. Compared to existing technologies, this system does not require laying during application.
