Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water pump control boxes, in particular to a control box and a fire water pump applying the same. Background Technique
[0002] The fire water pump system is the core guarantee of the building fire safety system, responsible for providing stable and sufficient fire water when a fire occurs. The reliability of its operation directly relates to the safety of people's lives and property. As the "brain" of this system, the fire water pump control box undertakes key functions such as start-stop control, status monitoring, fault alarm, and linkage response.
[0003] In order to facilitate the disassembly of the control box to quickly diagnose possible electrical faults in the water pump system (such as relay damage, fuse melting, etc.), the control box is generally designed to be detachable. For example, the Chinese patent "CN221670247U" discloses "a water pump control box and a water pump". The upper cover and the lower cover of the above control box are fixedly connected by self-tapping screws. However, when maintaining the inside of the control box, special tools are required for disassembly. At the same time, affected by the working environment of the water pump, if the self-tapping screws rust, they cannot be quickly removed, indirectly reducing the maintenance efficiency. Content of the Utility Model
[0004] Aiming at the deficiencies in the prior art, the utility model provides a control box and a fire water pump applying the same, which solves the problem that the existing control box is not easy to disassemble when connected by screws as a whole and is also affected by the environment.
[0005] On the one hand, according to the embodiments of the utility model, the following technical solutions are adopted:
[0006] The control box includes a base and an upper cover buckled on the base. The control box further includes a clamping block. A fixing seat is provided on the side of the base. The clamping block is movably arranged in the fixing seat. The fixing seat is provided with an installation groove. The end of the clamping block is bent to form a clamping portion, and the clamping portion protrudes from the installation groove. The upper cover is provided with a connection seat corresponding to the fixing seat, and the connection seat is provided with a connection hole. When the upper cover is buckled on the base, the clamping portion is clamped in the connection hole.
[0007] Compared with the prior art, the utility model has the following beneficial effects:
[0008] Since the clamping block is movably arranged on the fixing seat, the operator only needs to manually拨动 the clamping block to complete the locking and release of the upper cover. When locking, the clamping portion is clamped in the connection hole. When releasing, the clamping portion is separated from the connection hole under the rotation of the clamping block. In this solution, the clamping of the clamping portion and the connection hole is used to replace the traditional screw connection, eliminating the dependence on special tools such as screwdrivers, and enabling quick opening of the cover at the fault site, greatly shortening the fault diagnosis and emergency repair time.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0021] This utility model embodiment proposes a control box, including a base 1 and an upper cover 2 that is fastened to the base 1. The control box also includes a snap-fit block 4. A fixing seat 3 is provided on the side of the base 1. The snap-fit block 4 is movably disposed on the fixing seat 3. The fixing seat 3 has an installation groove 301. The end of the snap-fit block 4 is bent to form a snap-fit part 401, which protrudes from the installation groove 301. The upper cover 2 has a connecting seat 201 corresponding to the fixing seat 3. The connecting seat 201 has a connecting hole 202. When the upper cover 2 is fastened to the base 1, the snap-fit part 401 is snapped into the connecting hole 202.
[0022] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, all kinds of control components are installed in the base 1. The bottom of the base 1 has holes to facilitate the motor cable to pass through the base 1 and be electrically connected to some control components.
[0023] Since the locking block 4 is movably mounted on the fixed base 3, the movability can be either a rotational connection or a sliding connection. When the locking block 4 is movable, the locking part 401 at the end of the locking block 4 has both a locking state and a disengaged state. The operator only needs to manually move the locking block 4 to drive the locking part 401 to complete the locking and releasing of the upper cover 2. When locked, the locking part 401 is in the locking state and is locked into the connecting hole 202, thus limiting the upper cover 2. When released, the locking part 401 is separated from the connecting hole 202 under the rotation of the locking block 4, so that the locking part 401 changes from the locking state to the disengaged state, thus releasing the fixation of the upper cover 2. In this solution, the engagement of the locking part 401 and the connecting hole 202 replaces the traditional screw connection, eliminating the dependence on special tools such as screwdrivers. It can quickly open the cover at the fault site, greatly shortening the fault diagnosis and emergency repair time.
[0024] Based on the above solution, an elastic element is also included. This elastic element is located between the base 1 and the locking block 4. With the cooperation of the elastic element, the locking block 4 receives continuous elastic support. When the upper cover 2 is fastened onto the base 1, the locking part 401 automatically engages with the connecting hole 202 under the action of the elastic force, achieving quick and stable locking without additional operation. During disassembly, the locking block 4 is manually pushed to overcome the elastic force and disengage from the connecting hole 202 to complete the separation. The operation is simple and has an automatic reset function. Simultaneously, the locking block 4, under the continuous force of the elastic element, can be stably locked in the connecting hole 202. The aforementioned elastic element can be a sheet or a spring.
[0025] Preferred, such as Figure 2 As shown, the elastic element is a torsion spring 5. The end of the locking block 4 furthest from the locking portion 401 is provided with a mounting shaft 403. The mounting shaft 403 is rotatably mounted on the fixed base 3. The torsion spring 5 is mounted on the mounting shaft 403 and abuts against the base 1. The locking block 4 is rotatably mounted in the fixed base 3 via the mounting shaft 403, allowing the locking portion 401 to rotate around the mounting shaft 403. Simultaneously, under the action of the torsion spring 5, a stable elastic force is provided to the locking block 4 over a long period. Furthermore, a wedge 402 is fixedly provided at the top of the locking portion 401. The inclined design of the wedge 402 helps to guide the locking portion 401 during installation, making it easier for the locking portion 401 to enter the connecting hole 202 when installing the top cover 2, facilitating operation.
[0026] Based on the above solutions, such as Figure 2As shown, a rotating seat 6 is provided at the end of the base 1 away from the fixed seat 3. The upper cover 2 is rotatably mounted on the rotating seat 6. The upper cover 2 is hinged to the base 1 through the rotating seat 6, allowing the upper cover 2 to be rotated open instead of being completely disassembled. This improves the ease of operation for maintenance personnel. When inspecting, replacing components, or troubleshooting, it is not necessary to completely remove the upper cover 2, avoiding the loss or misinstallation of parts. Even when the control panel needs to be installed on the upper cover 2, the internal cables can be easily disconnected when slowly rotated open.
[0027] Specifically, such as Figure 2 As shown, the end face of the base 1 is recessed downward to form a groove, and a sealing strip 7 is provided in the groove. When the top cover 2 is closed and tightly fitted with the base 1, the sealing strip 7 can effectively prevent moisture, dust and other impurities from entering the control box, ensuring the cleanliness of the interior.
[0028] Specifically, such as Figure 1 As shown, the base 1 has several mounting holes 101 for bolts to pass through. By using bolts through the mounting holes 101, the base 1 can be fixed to the designated position of the motor, which can ensure a solid connection between the control box and the motor mounting surface and prevent displacement or tipping due to vibration, collision or other factors.
[0029] This embodiment also provides a fire pump, including the control box described above. The specific structure of the control box is the same as described in the above embodiment. Since this fire pump adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
